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 Fix Error Code 0x8007267C on Your PC

Error Code 0x8007267C – What is it?

Error code 0x8007267C is specific to Windows 10. This error is triggered when no DNS server is currently configured in your network settings during the Activation process. If you are fairly confident in your ability to address command-line tools and networking issues, you can follow the steps below to try to remedy the error code on your own. If not, you may need to contact a qualified technician in order to resolve the error successfully.

Solution

Error Causes

The cause of Error Code 0X8007267C within the Window 10 system is fairly straightforward. Windows Activation requires a valid DNS server to be configured in order to complete the Activation process; if one is not available or properly configured, then you may see this error code and Activation will fail.

Further Information and Manual Repair

The following methods may help you to resolve this error, but you’ll need to have some familiarity with command-line tools to complete the steps successfully. If these methods do not work or if you are uncomfortable in using the command prompt, you may need to consult a technician to fully resolve this particular error code on the Windows 10 system.

Method 1: Register a DNS server within your network properties and test the connection.

In order to resolve this error code, client connectivity to a DNS server must first be established. The following steps may help you to determine the root problem with your connectivity status:

Open a command prompt, after which you'll run IPCONFIG /all
Verify the following values: The IP address that has been assigned, the DNS server, the subnet mask, and the default gateway. Compare each to ensure that all are set with the values that correspond to your specific environment
Check for basic IP connectivity to the DNS server using the PING command. In using the PING command, utilize the address of the DNS server found in Step 1

ping <DNS Server IP address>

If basic connectivity to the DNS server in question is failing, then you will need to resolve that issue before going further in the process.

After troubleshooting the above basic connectivity issues to the DNS server, you can reattempt Windows Activation by using the command below from within an Elevated Command selection:

cscript windowssystem32slmgr.vbs -ato

If the steps above did not work for you, you may want to try the steps found in method 2.

Method 2: Use phone-based authentication with a MAK (multiple activation key).

If a DNS server is not connected to your network, you can use an alternative method to complete the Windows Activation process. Bypass Method 1 by using a MAK product key instead to activate the volume license installation. Certain MAK product key providers have a variation on the specific key numbers that you will need to use. If you are using TechNet media or MSDN media, you will have to change the product key listed to the product key provided. The product keys provided by either TechNet media or MSDN media for Windows Server 2008 or for Windows Vista Enterprise will be the MAK product key that you will enter in a later step.

Like the previous method, you will need to have some familiarity or confidence in your ability to operate Command Line tools before proceeding. Once you have found your MAK product key, you’ll need to open a command prompt and use the following command to change the product key to match the MAK product key, which should look something like the example below:

slmgr –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

After completing the product key change, use the following command to initiate the phone activation wizard, thereby completing the activation of the system:

slui 04

The activation wizard should be able to walk you through the remainder of the process in a step-by-step manner. In addition to appearing as an error code in Windows 10, this particular error may apply to multiple versions of Windows, including:

Windows 7 Enterprise
Windows 7 Enterprise E
Windows 7 Enterprise N
Windows 7 Professional
Windows 7 Professional E
Windows 7 Professional N

Steps to address the error code may be different in any of these other versions of Windows. If you have difficulty in resolving the error effectively, seek professional technical help.

Middle mouse button is not working

If you suddenly find the middle mouse button not working as you use it on your Windows 10 computer, then you’ve come to the right place as this post will provide some suggestions that can help you fix the issue. This kind of problem can affect your experience in using your computer as the middle mouse button helps you in scrolling through long web pages and screens with a lot of data. So if that stops, you will end up using your keyboard instead which is kind of a hassle compared to using the middle mouse button. It is possible that this problem could have something to do with either the hardware or software. To isolate the possibility of a hardware failure, you can try to connect the mouse to a different computer and see if it works just fine there or if it still has the same problem. If the mouse works properly on a different computer, then the issue is software-related. It is possible that a software update, especially gaming software, could have been misconfigured in a way that the middle button does not respond like it’s supposed to. To resolve the problem, you might want to try reinstalling or updating the mouse drivers or run the Hardware and Devices troubleshooter. You can also install OEM-specific mouse drivers or modify some entries in the Windows Registry.

Option 1 – Reinstall or update the Mouse driver

The problem may be caused by a corrupted or an outdated mouse driver. To fix it, you have to update or reinstall the mouse driver. How? Follow these steps:

Open the Devices Manager from the Win X Menu.
Then locate the Mouse and other pointing devices and right-click on the mouse driver to open the Properties.
After that, switch to the Driver tab and click on the Uninstall Device button.
Follow the screen option to completely uninstall it.
Finally, disconnect the mouse and plug it back in to reinstall the mouse driver.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 2 – Try running the Hardware Troubleshooter

The next thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:

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 3 – Try to install OEM specific mouse drivers

Aside from updating or reinstalling the mouse drivers, you might also want to try installing OEM-specific mouse drivers. When you install Windows, it will use a generic driver for all its components. The disadvantage of generic drivers for the mouse is that it limits its functionality. In fact, some also configure the middle mouse button to respond to specific action which does not work without the correct drivers. In such cases, you need to visit the website of your computer’s manufacturers to download and install the latest drivers and then open the software and configure it the way it was before. Keep in mind that some OEMs also offer gestures, so you also have to check on that.

Option 4 – Try to modify some entries in the Registry

If a Windows Update is the one that caused the problem, you could correct it by making some modifications in the Registry but before you proceed, make sure that you create a System Restore point first.

Tap the Win + R keys to open the Run utility.
Then type “Regedit” in the field and hit Enter to open the Registry Editor.
Next, navigate to this registry path: HKEY_CURRENT_USERControl PanelDesktop
After that, double click on the “WheelScrollLines” entry on the right pane to open its Properties.
Now change its value data to “3” and exit the Registry Editor and then see if the issue with the middle mouse button is fixed or not.

Potential issues with DRM and Alder Lake

We are all waiting for the release of Intel’s Alder Lake series of processors and real-world results on its performance. Sadly lately it came to our attention that some games might have issues with the processor.

Now before you go on the bandwagon on bashing Intel itself take note that it is not Intel’s fault at all. The issue that arises is mostly due to DRM software and how it works. As you might know or not, Alder Lake has two sets of cores, standard performance cores, and power cores, and with Intel’s Thread Director on-chip right cores will be used for the right tasks, and here lies the issue. DRM software might detect Thread Director as something suspicious and malicious, and then cut access to the game because of this. Intel, of course, has reached DRM manufacturers and places documentation about how software should be developed with this hybrid technology in mind. Of course, newer games will be updated if needed and everything will work fine, also games on GOG will work fine because of GOG’s policy of no DRM store but some older ones might be left in limbo. They could work fine but DRM might be triggered and prevent them from loading, usually, game developer itself removes DRM protection after some time but that is not really always the case and there is a chance that some games might simply just not work on Alder Lake CPU only because of DRM protection.

Conclusion

I will admit that I have not been a great fan of DRM in general, I understand that game developer want to protect themselves from piracy but how it looks they were not really successful with it. Even today single-player games get pirated on the day they are released and legally bought ones always make trouble for people that actually paid for them. I remember times when DRM was awful and you could install a game a limited number of times, luckily this was removed but it seems that many old habits still remain sadly and DRM is present even today in various forms. GOG is proof that people will buy DRM-free games and that they will support this kind of model. Maybe it is time to forget about fighting against piracy, you will not make it go away and people who do not want to buy games will not buy them, on other hand many users that do buy games, if they cannot use them they will rest to pirated version since that one will work. It is sad to see that pirated software can work better than a legal one and offer a more pleasant experience.

Sometimes Internal error code 2771 may appear during installation due to the leftover registry key from the previous Kaspersky software removal. A registry key is often created when uninstalling the previous Kaspersky version from the PC. This key is left behind even after you reboot your system. This key is called AVP**_post_ uninstall, you need to delete it to ensure the new version of the Kaspersky program is installed successfully on your PC. For this, simply go to the start menu and type Regedit in the search bar. Now navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun and then look here for the registry key called AVP**_post_ uninstall. In order to delete this file, right-click it and then select delete. Once uninstalled, reboot your PC and then try installing the Kaspersky Internet Security program again. Hopefully, this will resolve the issue. If the software installs smoothly, then the error is fixed, in case it still persists, then try other methods illustrated below.

Method 2 - Remove the INFCAHCE.1 Corrupt File

Another reason for the error pop-up may be INFCAHCHE.1 corruption. This file is basically used to store driver information and inf file locations. However, if it contains corrupted information, then you must remove it. To do this, go to the start menu and type cmd into the search bar. This will open a command prompt. Here type del C:\Windows\infinfcache.1. Now reboot your PC and try installing Kaspersky software on again.

Method 3 - Fix Software Conflict

Security software conflict can also result in internal error 2771 code display. And when this happens, the installation of Kaspersky prematurely ends. Security software conflict may occur if you have Comodo Firewall installed on your PC. A firewall is known to cause issues with Kaspersky software programs. The best way to resolve this issue is to uninstall all security software programs on your PC. Once all security software is removed, then install Kaspersky on your system. If the installation is successfully completed, then reinstall the other software again.

Method 4 - Download Restoro

Error 2771 can also result on your computer screen if traces of the previously installed Kaspersky software still remain in the registry despite the program removal.

Complete Ethernet cable guide

In today's modern world many households have internet access, most of the connection nowadays is done via Wi-Fi or wireless but there is a high probability that you have also a few devices connected via cable. There are of course many disadvantages and advantages between cable connection and wireless connection.

The main advantages of a hard cable connection are of course faster speed and stability compared to Wi-Fi. But if we look into the cables themselves there is also a big difference between them. Not all cables are the same and quality as well as speed vary a lot between them. Choosing the right cable is essential in order to make a maximum of your internet and we have some great tips and explanations of what cables do so you can make the right choice and enjoy your full internet potential.

Not all cables are the same

Cheap cables and expensive ones are not the same no matter what everyone tells you. The old proverb you get what you pay is true and more expensive cables will be made from better materials and will have a higher transfer rate.

Quality network cables are separated into different categories with proper markings and when buying one you should always look for these markings on the cables themselves, do not buy cables that do not have markings since they will often provide lower transfer rates or will not be shielded from outside influences resulting in packet drops and instability in a network.

Categories and what they mean are:

Cat-5 with a maximum speed of 100Mbps, typically unshielded.
Cat-5e with a maximum speed of 1Gbps, available in both shielded and unshielded varieties.
Cat-6 with a maximum speed of 10Gbps for runs under 55 meters (around 180ft), available in both shielded and unshielded varieties.
Cat-6a with a maximum speed of 10Gbps, shielded.
Cat-7 uses a proprietary GG45 connector rather than the standard RJ-45 connector seen on other cables for speeds of 10Gbps, shielded.
Cat-8 with a maximum speed of 25Gbps (Cat-8.1) or 40Gbps (Cat-8.2) at a distance of around 30 meters (around 100ft), shielded.

Unless stated, these standards are typically rated at their quoted speeds for a run of around 100 meters (around 330 ft) and use a standard RJ-45 Ethernet connector. Each generation of cable is designed to be compatible with the generations that came before it, so it’s possible (for example) to use a Cat-6a cable with a router that only supports speeds of 1Gbps.

Shielded cables

When purchasing higher quality cable you might not be able to choose if you have shielding or not since some standards like Cat-6a, Cat-7, and Cat-8 are always shielded. But if you do not have the need for these and you are satisfied with Cat-5e for example you can choose.

Shielded cables are a little more expensive but they will provide you with a coating that will eliminate interference from outside waves making cables more reliable. Of course, if the cable will go through a room that does not have many radio waves or some other interferences then buying a shielded cable is a waste of money.

Cable platings

Usually, there are two types of connector platings on connectors, silver, and gold, and people usually think that gold is much better but there are major differences between silver and gold platings and truth to be told there is no better one, both are different and should be considered depending on your need.

Silver plating will provide you with faster speed since its conductivity is larger than gold, but gold is slower on the oxidation front so its life span is longer. On the other hand, if your cables are always connecting and disconnecting gold will be first to be scrubbed off from the surface since the gold coating is much thinner.

Overall if you would only connect cable once and have slower internet than cable capacity gold is the way to go, in another case if you would use the cable as always connecting and switching and your internet plan is the same as cable transfer capacity you might want to go with silver one.

Cable material quality

Network cables are made from copper, your standard conduction material but even here there are differences in quality and therefore the chance of pocket losses over it. More quality less loss and more stable connection and this will depend on the purity of copper that is used in the cable itself. More purity in copper, more stability, simple as that.

Conclusion

So as you can see, there are a lot of different things that will influence your pick of proper network cable but the overall best advice is to get one that will fit well into your needs and setup. pair it up with your router and your internet plan since just simply buying something that you can not use is really a waste of money.
