What is MSIL/Filecoder.Chaos.C virus?

MSIL/Filecoder.Chaos.C is ransomware-type malware. It looks for the documents on your disk, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this malware additionally does a ton of damage to your system. It modifies the networking settings in order to prevent you from reading the removal articles or downloading the antivirus. In some cases, MSIL/Filecoder.Chaos.C can additionally stop the launching of anti-malware programs.

MSIL/Filecoder.Chaos.C Summary

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

  • Authenticode signature is invalid;
  • Anomalous .NET characteristics;
  • CAPE detected the Chaos malware family;
  • Encrypting the documents kept on the target’s disk — so the victim cannot use these files;
  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a major problem for the last 4 years. It is hard to realize a more damaging malware for both individuals and corporations. The algorithms utilized in MSIL/Filecoder.Chaos.C (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy already exists, and possibly will exist. But that virus does not do all these horrible things instantly – it may require up to a few hours to cipher all of your files. Hence, seeing the MSIL/Filecoder.Chaos.C detection is a clear signal that you need to start the clearing procedure.

Where did I get the MSIL/Filecoder.Chaos.C?

Routine ways of MSIL/Filecoder.Chaos.C spreading are typical for all other ransomware examples. Those are one-day landing websites where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait e-mails are a pretty modern strategy in malware spreading – you receive the email that imitates some normal notifications about shipments 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.

Avoiding it looks pretty uncomplicated, however, still demands tons of recognition. Malware can hide in different spots, and it is far better to prevent it even before it gets into your PC than to rely on an anti-malware program. Basic cybersecurity knowledge is just an important item in the modern-day world, even if your interaction with a PC remains on YouTube videos. That may save you a lot of time and money which you would spend while trying to find a fix guide.
