As you know, the Win + X menu, which is the shortcut context menu, is a useful way to launch several utilizes in Windows such as Power Options, Windows PowerShell, Event Viewer, Device Manager, and so on. However, there are times when you might experience difficulty in identifying the required utility. This is actually a part of the Windows 10 shell that goes out of scope in the customization of Windows 10. However, there is an easy trick you can use to do that. So in this post, you will be guided on how you can rename the options in the Win + X menu in Windows 10. In case you don’t know, the context menu is divided into three groups. Microsoft has categorized the bottom-most part as Group 1, while the middle part is categorized as Group 2 and the first part as Group 3. To rename these options, you need to use File Explorer and follow the instructions laid out below. Step 1: First, tap the Win + E keys to open File Explorer. Step 2: Next, navigate to this path: %LocalAppdata%MicrosoftWindowsWinX Step 3: From there, you should see three folders as Group 1, Group 2, and Group 3. Open the appropriate folder of your choice. Step 4: After that, right-click on the shortcut option you want to rename and then select Properties. Step 5: Next, navigate to the Shortcut tab under the Properties window. Step 6: Now in the text field of Comment, enter the new name of the option you selected. Step 7: Click on the Apply and OK buttons to save the changes made. Note: You can now either Sign back in or sign out of your Windows 10 User Account to see the result of the changes you’ve made. You could also restart the process of File Explorer via Task Manager. This will close the File Explorer as well as the shell components and then only launch the shell components again. In addition, you can check the Win + X menu to see the customized name that you’ve just set for a particular option. As you can see, even though it does not add anything extra, it is still a lot better in knowing how you can customize it.

Premiere Download Manager is a Browser Extension that comes bundled with Premiere Download Manager Potentially unwanted program, and other unwanted applications and extensions. This program was developed by Mindspark Interactive and offers users the ability to download files off the internet through the Download Manager provided. It also changes the home page and defaults the search engine to Myway.com.

This bundle monitors the user’s activity, and while the extension has access to your browsing activity, clicked links, visited pages, etc. the application itself has access to all the files that you downloaded, and have on your computer. This gathered data is later sent back to Mindspark’s servers where it is used to better target ads for users.

While installed, you will run into additional, sponsored links, and even pop-up ads while browsing the internet. Though it is not considered malware, it contains many behaviors disliked by users and is labeled as potentially unwanted. This bundle has been marked as a Browser Hijacker by several anti-virus applications and is therefore recommended to remove from your PC.

About Browser Hijackers

Browser hijacking is actually a form of unwanted software program, commonly a browser add-on or extension, which causes modifications in web browser’s settings. Browser hijacker malware is designed for many different reasons. Often, hijackers will force hits to sites of their preference either to increase web traffic producing higher ad revenue, or to obtain a commission for each and every user visiting there. Although it may seem naive, these tools are made by malicious people who always attempt to take full advantage of you, so that they can earn money from your naivety and distraction. Some browser hijackers are designed to make particular modifications beyond the web browsers, like changing entries in the computer registry and permitting other types of malware to further damage your computer.

Key symptoms that your internet browser has been hijacked

There are numerous symptoms that indicate your web browser is highjacked: the home page of the browser is changed all of a sudden; your browser is constantly being redirected to pornography sites; the default web engine has been changed and the browser security settings have been lowered without your knowledge; you’re getting browser toolbars you have never noticed before; you find lots of pop-up ads on your screen; your browser gets slow, buggy, crashes very often; You can’t access certain sites, in particular anti-virus websites.

Exactly how they get into your computer or laptop

There are several ways your computer or laptop can become infected by a browser hijacker. They generally arrive through spam email, via file-sharing networks, or by a drive-by download. They may also originate from any BHO, extension, toolbar, add-on, or plug-in with malicious purpose. Sometimes you may have mistakenly accepted a browser hijacker as part of an application bundle (usually freeware or shareware). Browser hijackers could affect the user’s web browsing experience significantly, monitor the websites frequented by users and steal financial information, cause difficulty in connecting to the net, and then finally create stability issues, making applications and computers freeze.

Removing browser hijackers

Certain browser hijacking can be quite easily reversed by finding and removing the corresponding malware application through your control panel. However, many hijackers are extremely tenacious and require specialized applications to eradicate them. Also, browser hijackers might modify the Computer registry therefore it could be very hard to restore all of the values manually, especially when you are not a very tech-savvy person. Installing and running antivirus applications on the affected system could automatically delete browser hijackers and also other unwanted applications. SafeBytes Anti-Malware discovers all types of hijackers – including Premier Download Manager – and removes every trace efficiently and quickly.

What To Do When You Cannot Install Safebytes Anti-Malware?

All malware is bad and the degree of the damage will differ greatly with regards to the type of malware. Certain malware variants modify internet browser settings by including a proxy server or modify the computer’s DNS configurations. When this happens, you’ll be unable to visit certain or all of the internet sites, and thus unable to download or install the required security software to get rid of the infection. If you are reading this article now, you have probably realized that virus infection is the cause of your blocked internet connectivity. So what to do when you want to download and install an anti-virus program such as Safebytes? There are some options you could try to get around with this particular issue.

Make use of Safe Mode to resolve the issue

In Safe Mode, you may change Windows settings, uninstall or install some applications, and get rid of hard-to-delete viruses and malware. In case the malware is set to load automatically when the computer starts, shifting into this mode could prevent it from doing so. To boot into Safe Mode, hit the “F8” key on the keyboard right before the Windows boot screen comes up; Or right after normal Windows boot up, run MSConfig, check the Safe Boot under the Boot tab, and click Apply. Once you are in Safe Mode, you can try to install your antivirus program without the hindrance of the malware. At this point, you can actually run the anti-malware scan to get rid of viruses and malware without interference from another application.

Switch to some other web browser

Some malware only targets certain internet browsers. If this sounds like your situation, employ another web browser as it can circumvent the computer virus. If you’re not able to download the anti-malware program using Internet Explorer, it means malware is targeting IE’s vulnerabilities. Here, you should switch over to a different internet browser like Chrome or Firefox to download Safebytes software.

Make a bootable USB anti-virus drive

Another option is to create a portable antivirus program onto your USB stick. To run anti-malware using a pen drive, follow these simple steps: 1) Download the anti-malware on a virus-free computer. 2) Plug the pen drive into the uninfected computer. 3) Double click on the downloaded file to run the installation wizard. 4) When asked, choose the location of the pen drive as the place where you want to store the software files. Do as instructed on the computer screen to finish up the installation process. 5) Transfer the USB drive from the clean computer to the infected PC. 6) Double-click the antivirus software EXE file on the USB flash drive. 7) Hit the “Scan Now” button to start the malware scan.

If you notice that your tabs in your Firefox browser keep on crashing recently, then there might be something wrong with your browser. Every time any of your tabs crashes, you might encounter an error message saying, “Gah, Your tab just crashed”. If you encounter this kind of error message then it is most likely that your Firefox Profile is having some issues with the existing installation of Firefox. The “Gah, Your tab just crashed” error rarely happens but when it does, it can get quite annoying as you won’t get to browse the internet peacefully. So to fix it, here are some suggestions you could check out.

Option 1 – Try disabling multi-process tabs in Firefox

Since Mozilla has one process for Firefox itself, while one process handles all the tabs, you have the option to disable these multi-process tabs in Firefox. To do that, follow these steps:

• In the address bar of Firefox, type “about: config” and hit Enter.
• Next, look for the following configurations and set them to false.
  • tabs.remote.autostart = false
  • tabs.remote.autostart.2 = false
• After that, double-click on the toggle switch between true and false.

Option 2 – Try checking your Add-ons

In this option, you need to start Firefox in Safe Mode and then check if the problem is fixed. If it is, you may have to check your Firefox add-ons as well as extensions as one of them might be the one that's causing the “Gah, Your tab just crashed” error.

Option 3 – Downgrade the Firefox version you’re using

It could be that the current version of Firefox you’re using has some issues so you might have to downgrade it, especially if you are already using the latest version. To downgrade your Firefox browser, go to the directory of the other versions and languages and select an older version that worked for you. After that, you have to disable automatic Firefox updates.

• First, click the menu button and select Preferences.
• Next, go to the Firefox Updates section under the General panel.
• Then select the radio button labeled “Check for updates but let you choose to install them”. This will ensure that you will not have the same issue with the new update.

Note that this is only a temporary fix since updating your programs, including browsers.

Option 4 – Try sending Crash Reports

You might want to send crash reports to Mozilla. This way, Mozilla might come up with some fix to resolve the problem. All you have to do is type “about: crashes” in the address bar. This will list all the crash reports. Now send it to Mozilla using the built-in interface. Although this won’t instantly fix the problem, a lot of user finds it useful. And besides, the issue will get fixed in future releases or with minor updates.

A lot of users rely on keyboard shortcuts to carry out tasks on their PCs. One of the most common keyboard shortcuts used is the Ctrl + Shift + Esc which opens the Task Manager. As you can see, the Shift key is not just used to capitalize a text as it can also be used for other functions and plays an essential role in operating a computer. However, if you suddenly find it not working, read on as this post will help you fix the problem. If your Shift key is not working, there are several potential fixes you can check out to fix it. These are the different ways to get rid of the Shift key not working issue on Windows 10:

1. Physically clean the key and keyboard
2. Disable Sticky Keys.
3. Update, Reinstall, or Rollback Keyboard driver.
4. Test the keyboard on another system.
5. Check your connections
6. Run the Hardware troubleshooter
7. Troubleshoot in Clean Boot State.

Option 1 – Clean the keyboard keys physically

Your keyboard might not be working properly due to some dirt or other corrosion. Thus, you need to clean your keyboard, especially the Shift key. First, you need to shut down your computer and then unplug the keyboard if you are using a desktop computer and then prepare it for cleaning. After that, use a small cotton ear cleaning tool to get between the creases and clean them. You can dip it slightly in alcohol to make it more efficient in cleaning dust and dirt. And if you can, you have the option to pull apart the keyboard completely and then wipe away all the corrosion from the inside. Once you’re done, put the keyboard back together and then plug it back into your PC. Now turn your PC on and check if the Shift key is now working.

Option 2 – Try to disable the Sticky keys

Another thing you can try is to disable the Stick keys. How? Refer to these steps:

• Tap the Win + I keys to open the Settings app.
• After that, navigate to the Ease of Access section, and here, select Keyboard.
• Next, make sure that the option for Press one key at a time under the Sticky Keys is toggled off.

Option 3 – Reinstall, update or rollback your keyboard driver

Once you’ve determined that the problem is in the software part of the keyboard, it is now time to try to reinstall, update or roll back your keyboard drivers. To reinstall the driver for your keyboard, refer to these steps:

• From the WinX Menu, open the Device Manager.
• In the Device Manager, you should find your laptop’s keyboard under the “Keyboards” option. Right-click on it and select the “Uninstall” option.

Note: If you’re not quite certain about your laptop’s keyboard, you can uninstall all the keyboards if there’s more than one.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – Run the Hardware and Devices Troubleshooters

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 7 – Put your PC in a Clean Boot State

You might also want to put your computer in a Clean Boot State to fix the problem with the Shift key. It could be that there is a third-party program that’s preventing the Shift key from functioning. To isolate this possibility, you need to put your computer in a Clean Boot State.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect the external devices and check if the error is now gone.

Error Code 36 – What is it?

This is a common Device Manager Error Code that users encounter. It is commonly found on all Windows 2000 and later versions of Windows operating systems. Error Code 36 is usually prompted by the following message:

"This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer's system setup program to reconfigure the interrupt for this device. (Code 36)"

Solution

Error Causes

Error Code 36 occurs when there is a failure in IRQ translation due to your Windows operating system getting corrupted. This is caused due to a number of triggers, such as:

• An excess of startup entries
• Errors in registries
• RAM or hardware failure
• Excessive unnecessary installed programs
• Malware or spyware

When programs are removed excessively, some programs are not removed completely and create problems in your computer’s registry.

Also, due to the presence of malware and spyware and other causes mentioned above, your computer registry builds up errors with the time that leads to slowing your PC, time lags, and even result in crashes and freezes.

Error Code 36 can cause internal and external components to malfunction or experience time lags such as DVD drive or printer and hence can severely affect your entire PC.

Further Information and Manual Repair

Error Code 36 is a severe PC error and any attempt at fixing the error must be approached with extreme caution for your PC to start functioning properly again. Here are two methods to fixing your PC.

Method 1 – Change IRQ reservation settings

Changing the IRQ reservation settings is the best way you can rely on to fix the error code. You can do this by changing the BIOS settings of your PC.

The BIOS stands for ‘Basic Input/Output System’ and is the program of your PC’s microprocessor that allows your PC to boot after you switch it on.

Caution needs to be exercised before changing the BIOS settings of your PC. This is because every PC’s BIOS version differs from another and any wrong attempt to change the settings may make matters worse.

It is therefore recommended to refer to hardware documentation that you received with your PC or motherboard and check for the model number and details of your PC’s motherboard.

Only after you have checked and confirmed all the details, should you use the specific BIOS settings required to configure your IRQ reservations?

Method 2 – Install DriverFIX

Error Code 36 isn’t an easy error to remove.

While changing the BIOS settings can work to restore your PC, it may create a whole lot of inconvenience for finding the time and effort to check the hardware documentation details and attempting to change the specific settings and especially, if your PC does not support the options to change IRQ reservations.

Given the high risks of fixing such an error, you can also install software that enables you to fix your slow PC at the click of a few buttons.

Programs such as DriverFIX can enable you to download and replace your outdated drivers with new updated ones without you having to look for them. It will detect which drivers to download based on your PC’s motherboard version from the program’s database and can get rid of error code 36.

Click here to download DriverFIX and remove error code 36 and any other type of Device Manager error from your PC.

If you are trying to access a particular file on your Windows 10 computer either to open, rename or delete it, and you suddenly encounter an error stating, “Could not find this item. This is no longer located in [Path]. Verify the item’s location and try again”, read on for this post will help you out in resolving this issue. If you are able to find and view a file on your computer, you should have clear access to it. And since you are seeing an error message when you try to do something about this file, you are not able to do anything with the file. There are times when this error pops up with the files created by third-party services and that the file’s extension is not defined properly. On the other hand, there are also other obscure causes for this error. To fix it, here are some suggestions you can try.

Option 1 – Delete the file using Command Prompt

If you wish to delete the problematic file and weren’t to, you can use Command Prompt.

• In the Start menu, type in “Command Prompt” to search for it or you could also click the search button right next to the Start menu and then right-click on the related result and select the option “Run as administrator”.
• Once you’ve opened Command Prompt, copy and paste the command given below and tap Entre after you do so. You also have to make sure that you key in the correct path where the file is located as well as its name.

rd /s \?X:badfolderpath Note: In the command above, “X” is the placeholder letter so you must input the letter that corresponds to the drive’s letter where the file is located.

• After that, you will see the “Operation completed successfully” message on your screen. If you don’t, check if you’ve really inputted the correct location of the file or its name.

Option 2 – Use a Command Prompt tweak to rename the file

If you don’t want to delete the file and only want to rename it, you can apply some tweaks using the Command Prompt. Make sure to follow the steps carefully.

• In the Start menu, type in “Command Prompt” to search for it or you could also click the search button right next to the Start menu and then right-click on the related result and select the option “Run as administrator”.
• After opening Command Prompt, type in “cd” followed by the path where the file is located with this format – “C:\Folder1\Folder2\Folder3”. However, you have to omit the problematic file this time. To put it simply, the last folder in the command must be the folder where the file is located.
• After inputting the command, tap Enter on your keyboard and then use the set of commands given below. Note that each command is a new line so you need to tap Enter after copying each line.
  • DIR /A /X /P
  • RENAME (the current name of the problematic file) (a non-problematic name)
  • EXIT

Note: Make sure that you only input the current name and the new name separated by a space. You must not write the brackets in the command. If everything goes well, you will now be able to operate the file like you used to before.

Option 3 – Use Command Prompt to delete the file without any extension

This option applies to cases where the affected file does not have any viable extension which means that Windows does not really know what to do with it and it only displays the “Could not find this item. This is no longer located in [Path]. Verify the item’s location and try again” error message. It usually occurs with the files created by browser plugins that are mostly from Mozilla Firefox. To delete these kinds of files, here’s what you have to do:

• Follow the first two steps from the previous option above so you can navigate to the location of the file accurately just be careful in inputting the folders.
• Don’t forget to tap Enter right after each command and then use the next command below so you can delete the affected file which has no extension:

del *.*

• After you’re done, open the File Explorer and then check if the file is now deleted or not.

Option 4 – Try using another workaround without using Command Prompt

This option is a lot like a workaround but it definitely gets the job done for you. It’s ideal for you if you do not want to deal with Command Prompt and only want to do everything in a graphical environment. To get started, follow the steps below.

• Look for the affected file or folder on your PC using File Explorer. Once you found it, right-click on it and select the “Add to archive” option from the context menu.
• Once the archiving options window pops up, look for the “Delete files after archiving” option and make sure that you select it then click OK to start archiving the folder or file. After that, you should now notice the file no longer exists.
• After that, delete the archive file as well.

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. Wondering what makes the world’s most secure computers so safe? See the Tech@Work guide: Upgrade to the World's Most Secure and Manageable PC

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. Need to up your remote work security game before there’s another entry on the list of most deadly computer viruses?

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. Can your printer get a virus? See our cool infographic: The State of Printer Security

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. Where will cybersecurity go next? See our guide: The Future of Cybersecurity

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.

A lot of Windows 10 users prefer the black theme on their computers and when you see anything but black it can get quite annoying. Such as is the case of the Taskbar which, as you know, is usually dark, however, when you take a look at the Cortana search bar, instead of seeing black, you’ll see that it has turned white. To fix this issue, read on as we will provide you some options you can try to set the Cortana search bar back to black. Before you proceed, take note that the options provided below will change all white search boxes to black and that one of these options needs administrative privileges.

Option 1 – Try changing the default App mode

As you know, Windows 10 has two modes, namely the Light and the Dark. Thus, you can switch to the Dark mode so that your Cortana search bar will be black as well. However, remember that it will completely change everything into dark mode so there will be no more Light mode elsewhere.

• First, you need to click on the Start button and then click on the cog icon to open the Windows 10 Settings.
• Next, from the Settings Menu, select Personalization and then select Colours from the left pane.
• Then scroll down until you see the “Choose your default app mode” option and select “Dark”.

After you apply the changes, it will change the Cortana search bar into black instantly. Aside from that, you will also see the User Interface changing into dark mode.

Option 2 – Try changing the Registry value

If you are well-versed in editing registry keys, then you need to try this option. But before you go over the steps below, make sure that you create a System Restore point first so that if anything goes wrong, you can always go back to how it was before the changes were applied.

• Tap the Win + R keys to open the Run prompt.
• Then in the field, type in “regedit” and hit Enter to open the Registry Editor. If a User Account Control prompt appears, just click Yes.
• Now that you’ve opened the Registry Editor, navigate to the following key:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionSearchFlightingWhiteSearchBox

• After that, double-click on the “Value” key located on the right pane and set the value to “0” instead of “1” and then click Ok to save the changes made. You should now see a black or grey text box color instead of white.

Option 3 – Try changing the Region

In some forums, a lot of users stated that changing the Region also worked out for them in changing the white Cortana search bar to white. Thus, you need to change the region settings of your computer temporarily. To do so, follow the steps below.

• Type in “Regional Settings” in the box and then click it as soon as it appears from the search results.
• Next, make sure to select a region where Cortana is not available.
• Then select apply to that region. After that, it will change the Cortana search bar color to black.
• Now sign out and sign back in and revert to the original settings. But the changes you made earlier in Cortana will still remain.
