VirLock Ransomware is probably one of the worst malware pieces you can get on your computer. It falls under the category of ransomware Trojans. What it will do is lock your computer so that you will be unable to use it. Then, it will require that you issue payment to its developers in order to get your files unlocked. It will also pose as a law enforcement agency, trying to trick users that they are in trouble with the law because they have installed pirated software.

VirLock Ransomware

If you get this malicious software on your computer, do not trust it, and do not do anything it tells you to. Instead, you should take immediate measures to remove it. The bad news is, however, that if you haven’t backed up your files, it will be quite challenging to decrypt them.

What Does Are the Effects of VirLock Ransomware?

So, once this infection enters your computer, it will lock it, rendering it unusable. Then, it will display a message saying that there are pirated materials on the PC. It will also claim that your system has been locked by a law enforcement agency. It will demand that you pay the fine in BitCoints (it will give you instructions on what to do), or go to your provincial courthouse, and pay the fine there. The first method will supposedly unlock your system instantly, while it will take 4-5 days for the latter one. It is easy to deduce which one users will choose. You should not do anything that this Trojan tells you. There are several reasons why you should not pay the ransom:

  • Your computer has not been locked because you have broken the law.
  • Even if you do pay the fine, there is no guarantee that your PC will be unlocked.
  • Paying will not remove the infection from your computer.

How Did VirLock Ransomware Get on My Computer?

VirLock Ransomware is a Trojan horse, which means that it is one of the most severe infections. It will not try to brute force its way onto your computer though. Trojans have to be helped by other malicious components in order to infiltrate your PC. Here are a few distribution methods used by VirLock Ransomware:

  • Spam emails. The emails will contain malicious attachments that can transfer exploit kits onto your computer that will then download the Trojan. The emails may also contain links to malicious websites that will target your system.
  • Malicious websites. As mentioned above, malicious websites can attack your PC, and spam emails are not the only way that you can end up on them. So you need to be really careful when browsing.

VirLock Ransomware can be presented as a useful piece of software. The infection can be disguised as some reliable program, but once you run its executable file on your PC, it will initiate its attack.

Files Attacked by Virlock Ransomware

Once Virlock has sneaked into the system, it will start ‘scanning’ it for certain file types:

    Executable files .exe
    Document files .doc, *.xls, *.pdf, *.ppt, *.mdb
    Archive files .zip, .rar
    Multimedia files .mp3, .mpg, .wma
    Image files .png, .gif, .bmp, .jpg, .jpeg, .psd
    Certificate files .p12, .cer, .crt, .p7b, .pfx, .pem

Once the desired files are located, VirLock will start encrypting them. It is also reported to add a .RSRC extension to affected files. The .RSRC section includes the resources employed by the executable. However, they are not considered part of the executable. VirLock uses the section to keep the resources of the host file.

How to Remove VirLock Ransomware

VirLock Ransomware is a severe infection, so removing it manually is not a good option, especially for non-expert users. So, your best option is to use a reliable anti-malware tool. However, the ransomware will try to prevent you from installing one. The best thing to do is to boot your PC in “Safe Mode with Networking,” and then install the security tool. You can have the installer on a flash drive, and install it from there. Once you have installed it, it will remove the ransomware completely. Then, it will continue to guard your system against malicious and stealthy software.
