What is MSIL/Filecoder.AFS virus?

MSIL/Filecoder.AFS is ransomware-type malware. It searches for the documents on your disk drive, ciphers it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this malware also does a ton of damage to your system. It changes the networking setups in order to avoid you from checking out the removal articles or downloading the anti-malware program. Sometimes, MSIL/Filecoder.AFS can also stop the launching of anti-malware programs.

MSIL/Filecoder.AFS Summary

Summarizingly, MSIL/Filecoder.AFS malware activities in the infected computer are next:

  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Ciphering the documents located on the victim’s drive — so the victim cannot use these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of security tools

Ransomware has actually been a major problem for the last 4 years. It is difficult to realize a more hazardous malware for both individual users and corporations. The algorithms used in MSIL/Filecoder.AFS (generally, 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 currently exists, and possibly will exist. But that malware does not do all these horrible things without delay – it may take up to a few hours to cipher all of your documents. Therefore, seeing the MSIL/Filecoder.AFS detection is a clear signal that you should begin the removal procedure.

Where did I get the MSIL/Filecoder.AFS?

Typical tactics of MSIL/Filecoder.AFS spreading are common for all other ransomware examples. Those are one-day landing websites where users are offered to download and install the free app, so-called bait emails and hacktools. Bait e-mails are a quite modern strategy in malware spreading – you get the e-mail that imitates some routine notifications about deliveries or bank service conditions modifications. Within the e-mail, there is a corrupted MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Preventing it looks fairly simple, but still requires a lot of recognition. Malware can hide in various places, and it is better to stop it even before it gets into your computer than to rely on an anti-malware program. Essential cybersecurity knowledge is just an important thing in the modern world, even if your interaction with a PC remains on YouTube videos. That can save you a great deal of money and time which you would certainly spend while searching for a fix guide.
