MSIL/Filecoder.BCL detection is a virus detection you can spectate in your computer. It frequently shows up after the preliminary actions on your computer – opening the untrustworthy email messages, clicking the advertisement in the Internet or setting up the program from dubious resources.

What is MSIL/Filecoder.BCL virus?

MSIL/Filecoder.BCL is ransomware-type malware. It looks for the documents on your disk drive, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents locked, this virus also does a ton of harm to your system. It modifies the networking setups in order to prevent you from reading the elimination tutorials or downloading the anti-malware program. In rare cases, MSIL/Filecoder.BCL can additionally prevent the launching of anti-malware programs.

MSIL/Filecoder.BCL Summary

In total, MSIL/Filecoder.BCL ransomware actions in the infected computer are next:

  • The binary contains an unknown PE section name indicative of packing;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Binary compilation timestomping detected;
  • Encrypting the files kept on the target’s drive — so the victim cannot use these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware apps

Ransomware has actually been a nightmare for the last 4 years. It is hard to realize a more hazardous malware for both individuals and corporations. The algorithms utilized in MSIL/Filecoder.BCL (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 terrible things immediately – it may require up to a few hours to cipher all of your files. Therefore, seeing the MSIL/Filecoder.BCL detection is a clear signal that you have to begin the removal procedure.

Where did I get the MSIL/Filecoder.BCL?

Typical methods of MSIL/Filecoder.BCL distribution are usual for all other ransomware examples. Those are one-day landing sites where victims are offered to download the free software, so-called bait e-mails and hacktools. Bait emails are a pretty modern strategy in malware spreading – you get the e-mail that imitates some routine notifications about shipments or bank service conditions updates. Within the email, there is an infected MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

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

Preventing it looks pretty simple, however, still requires tons of awareness. Malware can hide in various spots, and it is better to stop it even before it goes into your system than to trust in an anti-malware program. Common cybersecurity awareness is just an important thing in the modern-day world, even if your interaction with a computer stays on YouTube videos. That can save you a great deal of time and money which you would spend while trying to find a solution.
