10 Worst Computer Viruses in history

Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent.
Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server.

Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation.
Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught.

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging.
This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses.
As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last.
Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs.
The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter.

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch.
The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries.
The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms.

Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage.
Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red.

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic.
The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note.
The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million.

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack.
Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million.
Other notable viruses

The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years:

Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove.

Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India.

Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably.

Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather.

Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries.

Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.”

Explorezip: This worm used fake emails to spread to every machine on thousands of local networks.

Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million.

Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs.

Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates.

Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

How to create a public VPN Server on Windows

As you know, a Virtual Private Network or VPN is used to access a particular network from another network which is why it is also referred to as a mini-internet. Moreover, you can use it in two ways. One, you can use it to get you access to a closed server which means that you would not be getting access to the internet. Second, you can also use it to access a set of resources while at the same time get access to the internet. However, what if you want to access your resources at home even when you’re away? And what if you want to use the private server at home or at your office even when you’re away? This is where the callout for a VPN server for yourself comes in. And so in this post, you will be guided in how you can create a public VPN server on your Windows 10 computer. Follow each one of the given steps below to get started. Step 1: Find your IP address. This step is rather simple since all you have to do is open Control Panel > Network and Internet > Network and Sharing Center. From there, click on “Local Area Connection” and then click on Details where you’ll see your IP address next to “Autoconfiguration IPv4 Address”. Step 2: Next, set up port forwarding on your router. In this step, you will have to configure port forwarding in your router so that you would be able to connect to the VPN server through a public network like the internet.

Log in to the Admin Panel of your router. You have to do this since your router will be the gateway for your access to the network.
After you’re logged in, look for the “Port Forwarding” or “Applications and Gaming” or “NAT/QoS” menu tab and other similar names.
Now you need to set the port number to 1723 for connections based on Point to Point Tunneling Protocol.
Then save the configuration and reboot your router.

Step 3: Set up a VPN server on Windows 10.

In the Cortana search box, type “ncpa.cpl” and click on the related entry from the search results.
After that, tap the Alt + F keys to bring down the File Menu and then select New Incoming Connection which will open a mini window where you can allow the user accounts on the particular machine to access the VPN connection.
On the other hand, you can also click the “Add someone” button so that you can add someone else to the whitelist that can access the connection.
Now click on Next and you’ll see an option to select how people will connect to the network. Check the checkbox for the “Through the Internet” option.
After that, you will see a page where you have to configure the network. Just select IPv4 and then click on Properties.
From there, you will be asked to continue some additional settings like letting users access your Local Area Network or how IP addresses will be allocated to these users. Click on OK to save the changes you’ve made.
Click on Allow Access after you configure the network. And if you want to, you have the option to print this information for future reference or for the client machine.
Now click on Close to exit the configuration process.

Step 4: Allow the VPN Connections through the firewall In this step, you will have to allow the VPN connections through the firewall.

In the Cortana search box, type “Allow an app through Windows Firewall” and click on the related search result to open the intended Windows Firewall settings.
Next, click on Change Settings.
Then scroll down to check if Routing and Remote Access is Enabled for both the Public and Private networks and click on OK.

Step 5: Set up a VPN connection on Windows 10 Now all that’s left for you to do is to set up a VPN connection on Windows 10.

Go to Settings > Network and Internet.
From the list of options given, click on VPN located on the left pane to see the related settings.
After that, click on the “+” icon to add a VPN connection.
Next, select Windows Default under VPN Provider and under the Connection Name, input your VPN’s name, and then enter the IP address you got from the VPN service provider under the Server name or address section.
Now select PPTP under VPN type since it is the most commonly used protocol for VPNs.

Fixing DRIVER_IRQL_NOT_LESS_OR_EQUAL Stop Error on Windows 10

If you’ve been using your Windows 10 PC for a long time now, you might have come across a couple of issues – from minimal ones to critical ones like the Blue Screen of Death or BSOD stop errors. One of these BSOD errors you can encounter is the DRIVER_IRQL_NOT_LESS_OR_EQUAL Blue Screen error. This particular BSOD error is caused by iaStorA.sys, iaisp64 sys, Netwtw04.sys, nvlddmkm.sys, ndis.sys, wrUrlFlt.sys, and other driver files on Windows 10. This error indicates that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high. When you encounter this error, just like a typical BSOD error, your computer will abruptly stop and you will see a blue screen with an error message saying:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (100% complete) If you’d like to know more, you can search online later for this error: DRIVER_IRQL_NOT_LESS_OR_EQUAL (wrUrlFlt.sys)”

The iaStorA.sys file is a software component that’s related to the Intel Rapid Storage Technology by Intel. It is a software solution supported by Intel Smart Response Technology which allows the PC to communicate with the hardware as well as externally connected devices. The Intel Rapid Storage Technology enables the Peripheral Component Interconnect Express or PCIe storage support, serial ATA RAID or Redundant Array of Independent Disks 0, 1, 5, and 10 support, and the PUIS or power-up in standby is also supported. To resolve this kind of BSOD error, you have to update, roll back or fresh-install the problematic driver. Refer to the options laid out below for detailed instructions.

Option 1 – Try removing the Intel Rapid Storage Technology or IRST drivers

The first thing you can try is to fix the Wi-Fi driver or the Ethernet driver on your computer to resolve the BSOD error. Take note that this option works not only on Windows 10 but also other Windows versions.

Tap the Win + R keys on your keyboard to open the Run dialog box.
After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
After opening the Device Manager, click on the “IDE ATA/ATAPI Controller” entry and expand it.
Next, right-click on all the driver entries that are appropriately labeled, and then click on Uninstall device.
Now restart your PC and check if the problem’s fixed or not. If not, proceed to the next given option below.

Option 2 – Try updating the Intel Rapid Storage Technology or IRST drivers

If you’ve already tried uninstalling the IRST driver but you’re still getting the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error when you use your Windows 10 PC, then this means that the drivers might be corrupted or not compatible with the operating system version that you are using right now. So to fix the problem, you have to update your drivers. To do that, follow the steps below.

The first thing you need to do is to go to your OEM’s website.
Once you’re already on the OEM’s website, go to the Drivers section and get the latest version for your device and then try to overwrite it.

Alternatively, you can also update the drivers via the Device Manager:

Tap the Win + R keys on your keyboard to open the Run dialog box.
After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
After opening the Device Manager, click on the “IDE ATA/ATAPI Controller” entry and expand it.
Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
Now restart your PC and check if the BSOD error is fixed or not.

Option 3 – Try using the System File Checker via Command Prompt

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be causing the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error. To run the SFC command, follow the steps given below.

Tap Win + R to launch Run.
Type in cmd in the field and tap Enter.
After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

Windows Resource Protection did not find any integrity violations.
Windows Resource Protection found corrupt files and successfully repaired them.
Windows Resource Protection found corrupt files but was unable to fix some of them.

Server certificate revoked ERR_CERT_REVOKED!

While browsing the internet, if you suddenly encounter a warning with an error message saying, “Server certificate has been revoked ERR CERT REVOKED” then it indicates that the SSL certificate used by the website has been revoked by its issuer. This kind of problem can only be fixed by the website owner but that does not mean that you can’t do anything about it. In fact, you have the option to bypass this error as well as contact the certificate issuer – all this and more. Just a reminder, if a website that accepts payment, its passwords don’t have SSL or has some certification issue, you should never trust it. For instance, if you are trying to purchase something online and you’re on the payment stage but you encounter the “Server certificate has been revoked ERR CERT REVOKED” error, you must not proceed. To resolve the “Server certificate has been revoked ERR CERT REVOKED” error, here are some things you can do.

Option 1 – Try contacting the Certificate Issuer

If you are the website owner, of course, the best thing you can is to get in touch with the Certificate Issuer in order to resolve the problem.

Option 2 – Try fixing the Date and Time

You have to check your computer’s Date and Time. There are cases when this simple setting causes a connection problem. So if your computer Date and Time is set to date or time that this after the certificate expiration date, then you have to make sure that you set it to automatically configure time. To do so, just open Settings > Time and Language. From there, turn on the toggle for “Set time automatically” and “Set time zone automatically” options. After that, check if it fixes the error, if not, you need to check if the manual selection is correctly set or not.

Option 3 – Bypass the Certificate Revocation Check

As pointed out earlier, you have the option to bypass the Certificate Revocation check. All you have to do is follow the steps below.

In the search box of your browser, type “internet options” and open it once it appears.
After that, go to the Advanced tab and navigate to the Security subheading.
Next, uncheck the “Check for publisher’s certificate revocation” option as well as the “Check for server certificate revocation” option.
Now restart your computer. Upon the next startup, try opening the website again. This time, your browser will stop checking it for certificate issues. However, it’s not safe to leave those options unchecked so make sure that once the website’s SSL certificate is fixed or once you no longer have to visit that website, you recheck those options.

How to Manually Fix 0x8004210A Error Code on Your System

Error 0x8004210A - What is it?

0x8004210A is a typical POP3 email error message. This error may sometimes occur when you try to check your Post Office Protocol 3 (POP3) email account. 0x8004210A error code hampers your ability to both send and receive e-mails on your Outlook account. Error 0x8004210A is displayed in any one of the following formats on your PC:

The operation timed out waiting for a response from the receiving (POP) server 0x8004210a Task 'SMTP server name - Sending and Receiving reported error' (0x8004210A): 'The operation timed out waiting for a response from the receiving (POP) server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

Error Causes

Error 0x8004210A occurs due to several reasons. However, some of the most common reasons include:

Wrong port number for the POP incoming server
Your connection to the mail server is too slow
Incoming and outgoing emails are being scanned and stopped by an antivirus installed on your system
The Outlook send and receive job is being blocked by Firewall
You are sending and receiving large series of emails or large email attachments
Registry issues

No matter what the cause of this error is, to resume email communication via Outlook and to ensure your work productivity is not affected, it is recommended that you resolve this 0x8004210A error code on your PC immediately.

Further Information and Manual Repair

To fix error 0x8004210A, here are some of the most efficient and easy manual methods that you can try:

Method 1

If the cause of the error is related to the internet connection then here’s what you need to do. Try freeing up your internet connection by closing any other online activities in progress or downloads being carried on your system.

Method 2

Try to increase your server time-out periods. To do this, go to the Outlook File menu and choose account settings. Now double click on your email account and more settings. Now click advanced and increase your server timeout period to resolve.

Method 3

If you are trying to send or receive large and heavy emails on your Outlook account, the error 0x8004210A may pop up. This happens because when transferring heavy files the email account automatically locks until the task is complete, however, if it takes more time the next Send and Receive job starts while the first one is still not complete. In such an event, the email server then times out and shows you the error. Therefore to resolve, you will have to show patience. Simply wait for the large email to be sent or received before you start sending another email.

Method 4

If the antivirus installed on your system is the reason for the error pop up, then disable it for a while until the operation is complete. Then enable it once the task is performed successfully.

Method 5

Similarly, if the Firewall installed on your system is preventing Outlook from reaching your mail server, then simply disable the Firewall to resolve.

Chrome does not save passwords

Recently, a number of users reported that their Google Chrome browser does not remember any accounts, login sessions, as well as passwords. So if you are one of the users who experience the same problem, then you’ve come to the right place as this post will guide you on what you can do your Chrome browser does not save passwords, remember accounts and login sessions in Windows 10. This issue in Chrome could be caused by a lot of factors. It is possible that there is a setting in Chrome that prevents the browser from saving any data. It is also possible that the Google Chrome profile or the Cache folder for Chrome has become corrupted. Moreover, a third-party antivirus program could also be blocking the browser’s functionality in saving data. Whatever the cause is here are some suggestions you could follow that will help you fix the problem but before you do that, you can try to update your Chrome browser to its latest version first. If it didn’t work, then proceed to the given options below.

Option 1 – Try to clear browser cache

Open your Google Chrome browser.
After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
Now select every checkbox that you see and click on the Clear data button.
Then restart your Chrome browser and check if you can now complete the download again.

Option 2 – Try to delete the cache files for Google Chrome

The next thing you can do is to delete Chrome’s cache files or its store information which helps it in loading cached webpages faster when you pull them up. However, if it turns out that the cache files are corrupted, then it’s no wonder why Chrome is unable to save passwords. To fix this, you can try to delete the cache files for Google Chrome webpages and you can do it by following these steps:

First, open Google Chrome.
Next, open this address in Chrome – chrome://settings/clearBrowserData
After that, go to the Advanced tab and select all time as well as the first four options.
Now click on the Clear data option and then restart the Chrome browser once the cache has been cleared.

Option 3 – Try allowing Google Chrome to keep local data

If the option to keep local data is disabled in Google Chrome’s settings, it won’t be able to store local data in the browser. Thus, you need to enable it by following these steps:

Open Chrome and enter this address – chrome://settings/clearBrowserData
After that, drag the toggle button off for the “Keep local data only until you quit your browser” option.
Once done, restart Google Chrome and check it fixed the problem or not.

Option 4 – Try to enable the setting that offers to save password

As you know, a lot of websites offers users a choice to save a password and you can also do the same with the Chrome browser. You just have to enable this particular setting by going to the address, chrome://settings/passwords. From there, drag the toggle button for the setting Offer to save passwords, off.

Option 5 – Try to create a new profile for Chrome

If your user profile in Google Chrome ends up getting corrupted, it is most likely the reason why Chrome is unable to save passwords. Thus, you need to create a new user profile. How? Follow the steps below.

First, click on the account icon located at the top-right corner of the profile.
Next, go to the Manage People section and select Add Person > Add.
After that, enter the details to add the new account and then restart Chrome.

Option 6 – Reset Chrome

Resetting Chrome can also help you fix the problem. This means that you will be restoring its default settings, disabling all the extensions, add-ons and themes. Aside from that, the content settings will be reset as well and the cookies, cache, and site data will also be deleted. To reset Chrome, here’s what you have to do:

Open Google Chrome, then tap the Alt + F keys.
After that, click on Settings.
Next, scroll down until you see the Advanced option, once you see it, click on it.
After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
Now restart Google Chrome.

Option 7 – Try to clean reinstall Chrome

There are instances when programs leave files behind after you’ve uninstalled them and the same thing can happen to Chrome so before you reinstall Chrome, you have to make sure that you have deleted the User Data folder. To do so, refer to the following steps:

Hit the Win + R keys to open the Run dialog box.
Next, type “%LOCALAPPDATA%GoogleChromeUser Data” in the field and hit Enter to open the User Data folder.
From there, rename the default folder and name it something else, e.g. “Default.old”.
After that, install Google Chrome again and check if the issue is now fixed.

Fix Black background behind Folder icons

The File Explorer in Windows 10 provides several ways to organize the contents of folders and files in the system. Windows users can utilize some efficient styles to view the contents of the file system as per the user’s requirement. A user may opt to display the file picture in large size thumbnails while the other one could opt to set the icons of folder and files in a small or medium size list. On the other hand, while setting up several styles for the folder and file icons, some Windows 10 users have experienced some unusual issues where there is the Black background showing up behind folder icons. They tried refreshing the File Explorer a couple of times but it didn’t help in fixing the problem and the black squares are still visible on some folder icons. The black squares behind the folder icons might look disturbing though it’s not really a big problem and is merely a graphical glitch that does not cause any damage or whatsoever to the content of the folder and files. The most likely cause of this glitch might have something to do with the corrupted system files or it could also be caused by outdated thumbnail caches. In addition, graphical glitches like this one could also occur if you are using out outdated graphics drivers. To fix this problem, you need to follow the options laid out below.

Option 1 – Try using the Disk Cleanup to remove Thumbnail files

The Disk Cleanup tool is one of the options you can try to fix the black squares behind the folder icons. Through this tool, you can delete all the Thumbnail files on your disk. To use it, refer to these steps:

Open the Search bar and type “disk cleanup” in the field.
After opening Disk Cleanup from the search results, then from the drop-down menu select the C: drive to clean up and click OK.
Wait for the scanning process to complete. Once it’s done, select the files you want to delete.
Ensure that you select the box labeled “Thumbnails” under the Files to Delete section then click on OK.
After that, a confirmation box will appear, just click on Delete files to delete the files permanently.
Restart your PC.

Option 2 – Try resetting the Thumbnail cache

You have the option to manually delete the Thumbnail Cache to resolve the black square background behind the folder icons issue. Follow the steps given below to reset the Thumbnail cache.

Open the File Explorer.
Next, navigate to the View tab and select the option with Hidden items to display all the hidden folders and files.
Next, go to this path: C:Users<username>AppDataLocal
In the given path, make sure that you put your actual username in the username field. Then look for a file named “IconCache.db”. Right-click on this file and click on Delete.
After that, go to this path: C:Users<username>AppDataLocalMicrosoftWindowsExplorer
From there, select all the files and delete them.

Note: If a prompt appears saying, “The files are in use and cannot be deleted”, simply select the “Do this for all current items” option and then click on Try Again. If you get an error message, click on Cancel to close the window and restart your computer.

Option 3 – Try updating or reinstalling the Graphics driver

Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
Expand the section for the outdated device drivers.
And then select the outdated driver(s) and right-click on it/them.
From the drop-down menu, select the Update Driver option if you wish to update the driver or select the Uninstall device if you want to uninstall the driver and then follow the on-screen instructions to install the latest version of the driver.
Restart your PC after the installation to allow the system to reinstall the driver.

Upcoming Windows features for future

It is no secret that Microsoft is trying to keep Windows relevant and that it is trying to make it as good as possible. A new Windows update will bring some interesting stuff in it which well some like it, some not so much. Among various technical and security updates Microsoft will bring some directly visible to each user.

First

of these features will be File explorer compact mode. This feature is a sort of spacing content in file explorer giving it easier access if you are using a touch screen device. Now, this feature is somewhat strange, and altho I can understand and get behind the logic of this move I am not sure I like it. Lucky for me and others who feel the same this option can be turned off for now.

Second

feature is something I can get behind, improvements for virtual desktops. There is an article on errortools about virtual desktops feature and I really hope you are using it since it is a great feature. Anyway, new update will bring us separate desktop wallpapers for each desktop and we will be able to arrange them in order we like.

Third

thing that I would like to address is animation features. We will have windows slowly fade and resize when opened, minimized, maximized, etc. So far we are unable to tell how this can and will it affect overall system performance. I am sure it will have some impact but hopes are that it will be kept to a minimum.

Microsoft Surface Dial fails to pair with PC

One of the most interesting innovations that were released by Microsoft is the Surface Dial. This only goes to show that Microsoft is very competent not just in hardware but in overall innovation. Although it’s quite a piece of technology and as far as the consensus is concerned, it works pretty well, there are still some issues encountered by users. One of the particular issues experienced by users is that the Surface Dial fails to pair with every Windows 10 PC. At a time of writing, it is still not clear what the cause of the problem really is. However, their possible solutions are provided in this post that might help you resolve the problem. Before you get started troubleshooting the problem, make sure that there are two AAA batteries fitted inside properly.

Option 1 – Check if your PC supports Bluetooth 4.0 LE

In case you don’t know, the Surface Dial only works with the Windows 10 Anniversary Update and later PCs that support Bluetooth 4.0 LE. Thus, you have to check if this is supported or not before you troubleshoot further.

Tap the Win + R keys on your keyboard to open the Run dialog box.
Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
From there, click on Bluetooth and select “Microsoft Bluetooth LE Enumerator” from the drop-down menu. However, if it is not there, then it simply means that your computer does not support this standard which is most likely why you were unable to pair with other Windows 10 PCs. On the other hand, if you were able to see it, then proceed to the next troubleshooting steps below.

Option 2 – Check if Bluetooth is on

The next thing you have to do is to check if Bluetooth is turned on. As you know, the Surface Dial connects to your computer using Bluetooth and so you need to check if it’s really on or not. Aside from that, you also have to verify pairing.

Tap the Win + I keys to open Windows Settings.
Next, select Devices from the menu and click on Bluetooth.
After that, make sure that the toggle switch for Bluetooth is turned on.
Now all you have to do is to verify pairing by pressing and holding the pairing button located beside the batteries and then wait for a few seconds until the Bluetooth light begins to flash.
Then go back to the Bluetooth section and click on Bluetooth or other devices.
From there, click on Add Bluetooth and select Surface Dial.
Follow the next instructions on the screen and click on Done once everything is completed. That should fix the problem.

Option 3 – Check if Surface Dial is connected to another PC

If you think that connecting a Bluetooth device to two different PCs at the same time is wise, then think again as it does not really bode well for the overall user experience. Thus, you need to disconnect the Surface Dial from the system that you are currently using. On the other hand, if everything fails, then it’s most likely that the Bluetooth adapter is the one at fault. So you may have to get a third-party device that connects to your system via USB and then see if it works or not.

Linkury Smartbar Engine Removal Guide for Windows

Linkury Smartbar Engine is a Brower Toolbar for Internet Explorer. Upon investigation, we discovered that this toolbar does not work with the latest versions of Internet Explorer.

From the Author:

What the Smartbar does: – Changes the default search engine in your web browser’s built-in search box. – Changes the default home page of your web browser. – Adds alternative “page not found” functionality. – Enable search from the address bar of your web browser. – Allows software updates of the application once a new version is released. – Adds, removes, or modifies components interacting with search input fields.

While installed, users may see additional unwanted ads throughout their browsing sessions.

Several anti-virus applications have marked this toolbar as a Browser Hijacker, and it is not recommended to keep it on your computer, especially if you are using a newer version of internet explorer that renders this toolbar useless.

About Browser Hijackers

Browser hijacking means a malicious program code has taken control over and modified the settings of your browser, without your permission. Browser hijackers will do a number of things on a computer. These are typically used to force visitors to a particular site, manipulating web traffic to earn ad revenue. It may appear naive, but the majority of these sites are not legitimate and may pose a serious threat to your online safety. They did not just screw up your web browsers, but browser hijackers can also modify the system registry, leaving your computer susceptible to other attacks.

How you can determine if your browser is hijacked

When your browser is hijacked, the following could happen: home-page is changed; you see new unwanted favorites or bookmarks added, usually directed to advertisement-filled or pornography sites; the default browser settings are changed and/or your default web engine is altered; you find unsolicited new toolbars added; never-ending pop-up adverts appear and/or your web browser pop-up blocker is disabled; your web browser starts running slowly or exhibits frequent errors; you can’t visit specific websites like home pages of security software.

Precisely how browser hijacker infects computer systems

Browser hijackers could use drive-by downloads or file-sharing websites or perhaps an e-mail attachment in order to reach a targeted computer. They may also come from any BHO, browser extension, add-on, toolbar, or plug-in with malicious intent. A browser hijacker can be installed as a part of freeware, shareware, demoware, and fake programs. A good example of a well-known browser hijacker is the latest Chinese malware called “Fireball”, which has infected 250 million PCs across the world. It works as a hijacker but can be turned into a fully functioning malware downloader afterward. The existence of any browser hijacker malware on your system could substantially diminish the web browsing experience, monitor your internet activities that lead to serious privacy concerns, create system stability problems and ultimately cause your PC to slow down or to a nearly unusable state.

Removing browser hijackers

Some kinds of browser hijackers can be removed from your computer by deleting malicious software applications or any other recently added freeware. At times, it could be a tough job to find and eliminate the malicious program since the associated file could be running as part of the operating system process. Also, manual removals require in-depth system understanding and thus can be a very difficult job for novice computer users. Browser hijackers could be effectively removed by installing and running an anti-malware program on the affected PC. To eradicate any kind of browser hijacker from your laptop or computer, you could download this certified malware removal application – SafeBytes Anti-Malware. Utilize a system optimizer together with your anti-malware software to fix various computer registry problems, eliminate computer vulnerabilities, and enhance your computer's overall performance.

Help! Malware Blocking Anti-virus Installation And Access To The Web

Practically all malware is bad, but certain kinds of malware do a lot more damage to your computer than others. Some malware sits in between the computer and your net connection and blocks some or all websites that you really want to check out. It would also block you from installing anything on your machine, especially anti-virus software. If you are reading this now, you have probably recognized that a malware infection is the real cause of your blocked web traffic. So how to proceed if you need to download and install an anti-malware application such as Safebytes? There are some steps you can take to circumvent this issue.
