How to remove Ammyy Admin

Default applications in previous Windows versions were a pretty straightforward process. The user went to the settings application and picked for each category which application he would like to choose from the list of installed ones. In Windows 11 things are little changed. In this article, we will show you how to choose the default internet browser inside Windows 11, and sadly it is a more tedious task than in previous versions.

Choosing default browser in settings

As in previous versions of the Windows operating system you will need to use the settings application in order to change your default Internet browser. Previously, in Windows 10, a variety of general categories like email, web browser, and photo viewer were all listed under the Default Apps section of the Settings panel. It was easy to click on one of those categories and click on the option you like best from the small pop-up suggestion window. In the Windows 11 Insider Build, you’ll see a gauche list of an individual file or link types that you’ll need to specify your preferred browser for. The types include: HTM, HTML, PDF, SHTML, SVG, WEBP, SHT, FTP, HTTP, and HTTPS. There are additional optional types you can specify your preferred browser for as well. The issue here is in order to use a single browser which most users do you will have to go through each file type and set your preferred one. I am really not sure why this was introduced or why it has to be this way, all I can do is hope that in the final release of Windows 11 this feature will be rolled back as it used to be and that you could set your default browser in just one simple click.

One of the most useful and efficient command-line disk management tools is the DISKPART utility. It can be used to manage, delete or create new hard drive partitions. However, despite its efficiency, there are still times it could face some errors like the “No usable free extent could be found”. You can encounter this error when you create a partition. This error could be due to insufficient disk space which is why it is not able to carry out the operation. It is also possible that the disk is not recognized by the system. And since there are only four recognized primary partitions, when you try creating a fifth one, you will get this error. In addition, this error could also occur if the disk has been partitioned using the MBR disk partitioning format. To fix the “No usable free extent could be found” error, here are some suggestions you can follow.

Option 1 – Free up disk space using Storage Sense

The error could be caused by insufficient disk space in your computer and so you need to free up disk space using Storage Sense to fix the problem.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clear Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix Error 1310.

Note: You can also run the Disk Cleanup tool to free up disk space.

Option 2 – Try to run DISKPART in Command Prompt with administrator permissions

The next thing you can do to resolve the error is to run the DISKPART utility with admin privileges.

• In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
• Once you found it, right-click on it and select the “Run as administrator” option.
• After that, try to execute the Diskpart operation once again. Note that you also have to specify different size & offset values for the partitioning and then see if you still encounter the same error.

Option 3 – Try to execute the DISKPART clean command

The next thing you can try is to execute the clean command in DISKPART to fix any issues in the disk.

• Open Command Prompt with admin privileges.
• Then execute this command: diskpart
• The command you entered will initiate the DISKPART utility. Now execute this second command to view all the disk connects or all the partitions on those disks formed: list disk
• After that, you need to select one command depending on the list command you executed and then execute this third command: select disk #
• The third command you just executed will select the disk or partition you want to select. Now execute this fourth command: clean
• The command you entered will remove all the volumes or partitions formatting the disk in focus.
• Once it’s done, try to carry out the DISKPART operation you were trying to execute.

Option 4 – Try to update the USB drivers

Outdated USB drivers can also be the reason why you’re getting the error. Thus, you must update them from time to time. You can install the latest version of the USB driver for your system. But you need to check the manufacturer’s website or guidelines to update the driver according to your system. If it happens that the drivers might not be compatible with the version of the system your laptop is using which is unlikely, you can run the driver software in Compatibility Mode in that kind of situation. To update your USB drivers, follow these steps:

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, look for the USB Serial Bus controllers from the list of device drivers displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.

Option 5 – Run the Hardware and Devices troubleshooter or the USB troubleshooter

You can find the Hardware and Devices troubleshooter under the Troubleshooters section of the Windows Settings panel on your Windows 10 PC. You can use this troubleshooter to fix common hardware and external device-related issues without exerting too much effort. If you don’t know where to find it, follow these steps:

• Tap the Win + I keys to open the Windows Settings.
• Next, navigate to Update & Security > Troubleshoot.
• You should see the option for Hardware and Devices on your right-hand side where you can also find the “Rub the troubleshooter” button – click on it to get started.
• Follow the next on-screen instructions to fix the basic issues of common hardware and external device.

Note: If you want to, you can also use the USB Troubleshooter to fix the problem just go back to the Troubleshoot page where you can find it.

Instaling and removing applications from your Windows can sometimes leave some traces that are unpleasant and can cause annoyances. One of these annoyances is the program in the startup section of the task manager.

If you ever opened task manager and went into the startup section trying to disable some of the startup items on your Windows boot there might be a chance that you have experienced and seen a program without any icon or information about it just sitting there.

This is due to some applications being removed from the system but for some reason, it still shows itself in startup and it is quite annoying. So here we will show you how to get rid of this annoyance so your startup is clean again without junk in it.

Removing a program from startup

Locating the source of the issue

The first thing of course is to open the task manager itself and navigate to the startup tab. Inside the startup tab right-click on the column header and tick or enable Startup type and command line. Now you will see the location of the supposed file (that is missing or you could just go there by right-clicking on the item, but here it is greyed).

99% of the time startup type will be registry since the file is missing, if it was a file fix would be just to simply delete the file in the folder but since it was installed and not properly removed registry key is still present but the file cannot be found. After confirmation that the file is indeed missing and that the startup type is registry open the registry editor by typing Regedit in search and pressing enter.

Removing the key from registry

Inside Registry editor navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Inside on right part, you will see all auto-start entries added by installed applications.

Locate one that is causing issues by comparing its path with the path inside the task manager command line and delete the key. Once the key is deleted right-click on RUN on the left part and choose HKEY_LOCAL_MACHINE to quickly jump on that key location and repeat the process of key deletion if needed. HKEY_LOCAL_MACHINE will delete startup entry for all users and sometimes entry will not be present here since the application is not installed for all users or there are no other users on the machine.

After the procedure is finished, reboot your systems in order to apply changes.

It is a fact that Google Chrome is one of the world’s most used web browsers and it’s because this search giant is focused on following the standards of the web. Although this web browser has become quite bloated over the years, it still remains at the top of the list of browsers used most by users. If you are a user of Google Chrome for a long time now, you have most likely come across a couple of issues in the past while using this browser. In this post, we’ll help you fix one of the issues commonly encountered in Chrome which is the “No Data Received – ERR_EMPTY_RESPONSE” error. This kind of error message in Chrome pops up when you try to log into a website. It isn’t clear what’s the cause of this error but worries not, for there are several ways you can try to fix it.

Option 1 – Try checking if your network connection is working

The No Data Received – ERR_EMPTY_RESPONSE error is not usually related to a downed network. However, anything is possible so you need to check if your internet connection is working just fine or not as it might be the reason why you’re getting this error in Chrome.

Option 2 – Try resetting the network

There are instances when a network goes into haywire because of a bad DNS. Thus, a bad DNS might be the one that’s causing this headache so it’s time for you to reset the entire network to resolve the issue. To reset the network, here’s what you have to do:

• Click the Start button and type in “command prompt” in the field.
• From the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After opening Command Prompt, you have to type each one of the commands listed below. Just make sure that after you type each command, you hit Enter
  • ipconfig /release
  • ipconfig /all
  • ipconfig /flushdns
  • ipconfig /renew
  • netsh int ip set dns
  • netsh winsock reset

After you key in the commands listed above, the DNS cache will be flushed and the Winsock, as well as the TCP/IP, will reset.

• Now restart your computer and open Google Chrome then try opening the website you were trying to open earlier.

Option 3 – Try to clear the browsing data of Google Chrome

If your browsing data in Chrome hasn’t been cleared for some time now then that might be the reason why you’re suddenly getting the ERR_EMPTY_RESPONSE error when you browse the web. To fix this error, you need to clear your web browsing data. Refer to the following steps to do so.

• Tap the Ctrl + Shift + Delete buttons to go to the Clear browsing data section in Chrome.
• Next, set the time range to “All time” and tick all the boxes and then click on the Clear data button.
• After that, restart the Chrome browser and try to open the website you were trying to open earlier.

Option 4 – Reset Google Chrome

If none of the options given above worked, you can try resetting the Chrome browser. To do that, follow these steps:

• 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 an option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Restart Chrome and check if you can now open the webpage or not.

In today's age, free cloud storage is no longer anything exclusive and plenty of companies will offer some free amount of it in hopes that you will buy a premium plan. Among plenty of starter and free options, there are of course some that are more generous and more appealing and offer a larger quantity of free space and even some other services.

In this article, we are taking a look and recommending some of the best ones in our opinion.

Google drive

First on the list is of course google with its google drive. With an amazing 15GB of free could storage just given to anyone who makes a google account this had to be the first recommendation. Also since google drive is requiring a google account you will be given all google office tools for free as well as the Gmail service. Completely free 15GB at your fingertips if you do not mind google tracking policies.

Microsoft one drive

Another company on the list, with only 5GB storage seems little compared to google this entry was simply included because google Microsoft also offers you Office 365 WEB for free with skype along with their Hotmail. So all in all another full package of apps with some free storage that requires also just an account.

IceDrive

With the free offer of 10GB this comes as an easy recommendation, IceDrive is a cloud storage company that is not offering anything of productivity apps but it has some great features in their cloud solution like being able to see encrypted files in your cloud. All you have to do to get this 10GB of storage is to make a free account.

MEGA

With an amazing 20GB of free storage, MEGA is certainly one that gives the most space for free. Sadly a few years ago it was hacked and files and user information were leaked, for that reason, it is on our last place of recommendation but if you are not worried about their security and plan just to use this as a temporary file sharing service with that amount I am sure it will fill your needs.

Email Access Online is a browser extension published by Polarity Technologies Ltd. That offers users quick and easy access to emails and weather reports. While this might sound interesting and useful, there is nothing this extension offers that cannot be solved with a few simple bookmarks.

While installed Email Access Online monitors the user's browser activity and records visited websites, clicked links, and bought products, this data is later used to serve partner ads if the user looks for the covered categories, additionally, it will hijack your new tab page, changing your search engine to Yahoo to allow easier ad placement.

Browsing the internet with this extension enabled will result in additional ad placement, pop-up ads, and sponsored links throughout your browsing sessions.

Upon further investigation, it was discovered that this extension is a repack of MyEmailXP, which was a repack of Fast Email Checker. Due to its suspicious delivery methods and information gathering, several anti-virus scanners have marked this extension as a browser hijacker and it is recommended to remove it from your computer.

If we are to believe news from Intel, new series of processors based on Alder Lake architecture are about to be released somewhere in October. Alder Lake is the 12^th Generation Core of Intel processors and it is meant to have all advantages of the current CPU structure. I9 is aimed to pack a punch against its competitors with technology including eight high-performance Golden Cove cores (P-cores) with Hyper-Threading and eight energy-efficient Goldmont (E-cores) equipped with a 30MB L3 cache and operating at high clock speeds. During the benchmark test, the new CPU outperformed all of Intel’s previous Rocket Lake structure processors which is logically expected but the big surprise came from results that indicate better performance than Apple’s new M1 processor even in single-threaded performance which is supposed to be best in that field. Another surprise was really beating AMD Ryzen 9 in each field. If we take into account that i9 has 16 cores in total and can process 24 threads against Ryzen 9 with 16 Cores and 32 threads this is an impressive feature. Now truth to be told Alder lake has massive L3 cache and microarchitectural advantages and consumes much more power but the results of performance are high. Also, note that this early CPU is not really a mass production one and maybe some things will still change but early results are very satisfactory. We will see what will price tag be since in this age of shortage and competition that will also play a big role in its overall success. Speaking of competition I eagerly await AMD’s response to this, in any way it seems that the CPU market is for some turbulence which is always a good thing for the final customer and I welcome it.

As of late, many users reported getting an error in Windows Sandbox that has an error code of 0x80070015. According to users, they encountered this error when they tried to start Windows Sandbox. Based on the error code, it seems that there are some problems with the supporting services of Windows Sandbox that trigger the error. It is possible that these services are misconfigured or that they are outdated and have to be updated. Here’s the complete message of the error:

“Windows Sandbox failed to start. Error 0x80070015. The device is not ready. Would you like to submit feedback about this issue?”

If you are one of the users who encountered this kind of error in Windows Sandbox, then you’ve come to the right place as this post will help you sort this problem out. All you have to do is follow each one of the options provided below.

Option 1 – Make sure that all the supporting processes and services of Windows Sandbox are running properly

If running Windows Sandbox as an administrator didn’t fix the error, you have to ensure that all related processes for Windows Sandbox are running properly. To do that, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.

• Once done, try to open the Windows Sandbox again and see if the error is fixed or not.

Option 2 – Try to install any pending Windows Updates

If the second option still didn’t work, then you might want to check Windows Updates on your computer and see if there are any pending Windows Updates you have to install. All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox Error 0x80070015.

Option 3 – Try to run Windows Sandbox as an admin

• Next, if a User Account Control or UAC prompt pops up, just click on Yes to proceed.
• You should now be able to open the Windows Sandbox without the error. However, if the error persists, proceed to the next given option below.

Error code 0x8007007b - What is it?

Error code 0x8007007b will present itself when Windows users are trying to activate Windows. You may try to activate it through the update and security option, but it is likely that you will receive the same error code. Error code 0x8007007b may be presented when Windows 7 and Windows 8.1 users try to upgrade and activate Windows 10 on their computer.

Common symptoms include:

• An error message will display that says Windows cannot be activated. The KMS host cannot be located in the DNS, please have the system administrator verify that the KMS is published correctly in DNS.
• Error 0x8007007b will be displayed, stating that the file or directory name or the volume label syntax is not correct.

Solution

Error Causes

There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

• Click Start, type in regedit, and then press Enter.
• Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
• The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

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?

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.
