What is Win32/Virlock.AN virus?

Win32/Virlock.AN is ransomware-type malware. It looks for the documents on your computer, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files inaccessible, this malware also does a lot of harm to your system.

Win32/Virlock.AN Summary

Summarizingly, Win32/Virlock.AN ransomware activities in the infected computer are next:

  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Anomalous binary characteristics;
  • Ciphering the files kept on the target’s disks — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-virus programs
  • Blocking the launching of installation files of security tools

Ransomware has been a headache for the last 4 years. It is challenging to imagine a more hazardous malware for both individual users and companies. The algorithms utilized in Win32/Virlock.AN (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy already exists, and possibly will exist. But that virus does not do all these terrible things instantly – it can require up to several hours to cipher all of your documents. Thus, seeing the Win32/Virlock.AN detection is a clear signal that you need to start the removal procedure.

Where did I get the Win32/Virlock.AN?

Typical ways of Win32/Virlock.AN spreading are typical for all other ransomware examples. Those are one-day landing websites where victims are offered to download and install the free app, so-called bait emails and hacktools. Bait emails are a quite modern method in malware distribution – you get the e-mail that mimics some standard notifications about shipments or bank service conditions changes. Within the email, there is an infected MS Office file, or a web link which leads to the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks pretty easy, however, still requires tons of focus. Malware can hide in different places, and it is far better to prevent it even before it goes into your PC than to rely upon an anti-malware program. Essential cybersecurity knowledge is just an important item in the modern world, even if your interaction with a computer remains on YouTube videos. That may keep you a lot of money and time which you would spend while looking for a solution.
