WebShield Malware Removal Tutorial

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.

The latest steam beta update has introduced code that will prevent downloading and installing previous game versions via the steam client. For many people that are playing online games, this is not such a big deal since they always must have the latest version in order to play their games but for other ones, this has arrived as a bit of a problem. Many people preferred older game versions since often updates can change certain mechanics inside the game making it different as an experience or introduce some elements that not everyone likes. So far, people could use the steamDB site to find depo of the game versions you would like to play and download it but if this beta code goes live that will not be an option anymore. Now, playing old games without updates could also be used for nostalgic reasons and these people have also been cut off with this update. It is important to point that update is still in beta client only but users have already started to voice their opinions asking Valve not to place it live. In the end, it will all depend on Valve’s decision will they listen to their customers or decide to push updates on live service.

When you try to open Outlook 20016 and other programs on your Windows 10 PC and end up getting an error instead saying, “Failed to register a VB Script DLL. Reinstall or run Regsvr32.exe Vbscript.dll to self-register”, read on as this post will help you resolve the problem and help you re-register the vbscript.dll file.

Afraid of the growing threats online? As you should be. But we’re here to show you what kinds of malware are out there and what you can do to keep them at bay.

Malware definition

Malware comes from the term malicious software. It’s software designed to attack and exploit devices and networks to the advantage of the hacker who made it.

Malware can be transmitted in different ways. Most commonly this happens via infected USB drives, downloadable files or malicious websites. Depending on the type and ultimate goal, the consequences of a malware attack can range from negligible to catastrophic.

What kinds of malware are there?

1. Virus

A virus is typically spread via infected files, websites or links. It’s one of the oldest malware types and one of the most difficult to get rid of. That’s because, once activated, it replicates itself - hence the name. 

It can perform different kinds of attacks, depending on what the creator wants to achieve. The main characteristic of a virus is that it really doesn’t show itself until you activate the host. So that’s a scary thought for sure.

2. Adware

Sometimes an ad blocker isn’t enough to fight off unwanted ads. And some of them can, unfortunately, be malicious. They may redirect you to infected sites or prompt downloads of risky files. Even just opening a malicious site can lead to data theft.

So, definitely be careful when clicking around. Even if an ad seems completely legitimate, you can never be too sure.

3. Ransomware

Through ransomware, cybercriminals gain access to a user’s data and use it to extort them for money. Basically, the user is threatened with data deletion or even exposure if a ransom isn’t paid by a specific deadline.

This is a particularly nerve-wracking type of malware. If it targets an individual, it preys upon their sense of anxiety, fear, guilt and even shame. If it targets a business (which is a lot more common), it preys upon not only that business’s profit but also every single one of their customers and their data.

4. Trojans

This type of malware disguises itself very well as a legitimate-looking program. Once you download it, hackers can get full access and control of your device, data and network. They can even be hidden in games, apps and attachments. They cannot self-replicate, though, so we guess that’s… good news?

5. Worms

Worms can replicate, just like viruses, but you don’t need to actually activate the infected program for them to get going. They can be used for various purposes, ranging from data deletion to file encryption to support a ransomware attack.

6. Spyware

Spyware refers to malicious software that stays hidden on your computer and monitors your activity. The best-known type is keyloggers. This can be used to steal sensitive data like passwords and banking information.

7. Rootkits

Rootkits are among the most dangerous types of malware. They allow administrative access and full control of a device, which lets hackers continue hijacking all your data and monitoring your activity without your knowledge.

8. Botnets

Botnets are networks made up of bots - computers that cybercriminals have infected with malicious software. Bots and botnets give hackers remote access to users’ devices and allow them to spy on your camera, take screenshots, memorize passwords and launch Distributed Denial of Service attacks. This one truly makes your hair stand on end.

What can you do about it?

You know the old adage - better safe than sorry. And trust us, malware attacks are such a pain in the you-know-what that you really don’t want to be sorry.

Luckily, there are simple solutions that can shield you from most digital threats these days. What you want to be looking at is a solid antivirus program. Well, technically, you need an antimalware program, but since the latter evolved from the former, we still mostly refer to them as antivirus software.
The majority of antimalware programs these days don’t just shield you from potential risks online, but include additional features as well. For example, some Bitdefender antivirus packages also include parental control and a VPN. And Bitdefender is not just for PCs either - it offers protection for your beloved iPhone or Android as well. You can throw in a password manager in there too, for an additional layer of security.

If you aren’t too concerned about all these various threats or feel like you don’t need extra security, you can at least take a step to protect your information from being exposed to lurking cybercriminals as you’re browsing. This can be done through a good VPN like Surfshark, which hides your identity in the digital space and prevents your data from being tracked.

Choosing the right protective software is especially important if you have children with access to the Internet, since they’re unfortunately even more vulnerable to malicious attacks. If you aren’t sure what the right kind of antimalware program is right for you, you can reach out to us and we’ll be happy to help keep your entire household or office digitally secure.

The bottom line

The truth is that there’s no way to be 100% protected in the online world. Hackers are constantly coming up with new ways to infiltrate our devices. But malware-battling software evolves along with them and there’s still plenty you can do to keep risks away. Stay safe!

There are times when you suddenly encounter a Blue Screen error like DRIVER_POWER_STATE_FAILURE error when resuming from Sleep or right after you shut down or restart as well as switch from Hibernate mode. This kind of Blue Screen error is due to some issue with the driver state. Moreover, the bug check “0x0000009F” in the error also indicates that a driver is in an inconsistent or invalid power state. The DRIVER POWER STATE FAILURE Blue Screen error usually occurs during events that involve power state transitions like shutting down, moving in or out of standby mode, or hibernate mode. To resolve this error, you can check out the suggestions given below.

Option 1 – Update the Device drivers

The device driver installed in your computer might be incompatible with your operating system which is the reason why the DRIVER POWER STATE FAILURE Blue Screen error occurs. To fix that, you have to update your device drivers.

• Reboot your computer into Safe Mode with networking support.
• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, update all the outdated Device drivers on your computer.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if the BSOD error is fixed or not.

Option 2 – Uninstall any faulty device drivers

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “msc” in the field and hit Enter or click OK to open the Device Manager.
• From there, look for any device driver which has a yellow exclamation mark which indicates that something is wrong with them.
• And then right-click on each one of them and click on Uninstall.
• Once you’re done uninstalling the faulty drivers, restart your computer and allow your computer to reinstall the drivers you just uninstalled.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like rtwlane.sys Blue Screen error. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 4 – Try to remove external hardware

If there is any external hardware plugged into your computer especially the new ones, you can try removing it and then check if the Blue Screen error persists. If the problem gets solved, you might want to update the driver of that particular hardware. On the other hand, if you’re still getting the error, then proceed to the next given options below.

Option 5 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.

Option 6 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the DRIVER POWER STATE FAILURE Blue Screen error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.

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

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

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

Windows 10 supports various devices to get connected to which makes it quite a flexible operating system. The connection varies on the fact that the device can be connected either with Bluetooth or other wireless and wired connection. However, no matter how great the features are, there a few times when they bring in some bugs too. One of these bugs won’t allow you to either remove or reinstall the Bluetooth mouse and keyboard device from your Windows 10 computer. So if you are currently experiencing this problem, read on as this post will guide you in fixing it. Before you go over the suggestions laid out below, you need to create a System Restore Point first since, in one of the options, you will be making some changes with the registry files as well as some critical Windows settings. Once you have that covered, refer to the following options.

Option 1 – Configure the Bluetooth Services

The first thing you can do is configure Bluetooth Services.

• Tap the Win + R key combination to open the Run dialog box.
• After that, type “services.msc” in the field and hit Enter to open the Windows Services Manager.
