MSIL/Filecoder.YN detection is a malware detection you can spectate in your system. It frequently appears after the preliminary actions on your PC – opening the dubious e-mail messages, clicking the banner in the Internet or mounting the program from untrustworthy sources. From the instance it shows up, you have a short time to do something about it until it starts its harmful action. And be sure – it is far better not to wait for these harmful effects.

What is MSIL/Filecoder.YN virus?

MSIL/Filecoder.YN is ransomware-type malware. It searches for the documents on your disk drive, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your files locked, this virus also does a lot of damage to your system. It modifies the networking settings in order to avoid you from checking out the elimination manuals or downloading the anti-malware program. Sometimes, MSIL/Filecoder.YN can even block the setup of anti-malware programs.

MSIL/Filecoder.YN Summary

In summary, MSIL/Filecoder.YN ransomware activities in the infected PC are next:

  • Dynamic (imported) function loading detected;
  • Authenticode signature is invalid;
  • Encrypting the files located on the target’s drives — so the victim cannot use these files;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of security tools

Ransomware has been a headache for the last 4 years. It is difficult to imagine a more harmful virus for both individual users and corporations. The algorithms used in MSIL/Filecoder.YN (typically, 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. However, that virus does not do all these horrible things without delay – it can take up to a few hours to cipher all of your files. Thus, seeing the MSIL/Filecoder.YN detection is a clear signal that you should start the elimination procedure.

Where did I get the MSIL/Filecoder.YN?

General methods of MSIL/Filecoder.YN distribution are basic for all other ransomware examples. Those are one-day landing sites where victims are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a quite modern tactic in malware spreading – you get the e-mail that simulates some normal notifications about deliveries or bank service conditions changes. Inside of the email, there is a corrupted 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 quite uncomplicated, however, still demands a lot of attention. Malware can hide in various places, and it is far better to prevent it even before it goes into your system than to rely upon an anti-malware program. General cybersecurity knowledge is just an important thing in the modern-day world, even if your interaction with a PC remains on YouTube videos. That can keep you a great deal of time and money which you would spend while trying to find a solution.
