What is MSIL/Filecoder.APX virus?

MSIL/Filecoder.APX is ransomware-type malware. It looks for the files on your disks, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents inaccessible, this malware additionally does a ton of harm to your system. It alters the networking settings in order to prevent you from reading the removal manuals or downloading the antivirus. In some cases, MSIL/Filecoder.APX can even block the launching of anti-malware programs.

MSIL/Filecoder.APX Summary

In summary, MSIL/Filecoder.APX malware activities in the infected computer are next:

  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Anomalous .NET characteristics;
  • Ciphering the documents located on the victim’s drive — so the victim cannot check these documents;
  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-virus programs

Ransomware has actually been a nightmare for the last 4 years. It is challenging to imagine a more hazardous malware for both individual users and businesses. The algorithms utilized in MSIL/Filecoder.APX (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. However, that malware does not do all these terrible things immediately – it can require up to several hours to cipher all of your documents. Thus, seeing the MSIL/Filecoder.APX detection is a clear signal that you need to begin the elimination procedure.

Where did I get the MSIL/Filecoder.APX?

Common ways of MSIL/Filecoder.APX injection are standard for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a pretty new method in malware distribution – you get the email that imitates some regular notifications about deliveries or bank service conditions updates. Inside of the email, there is an infected MS Office file, or a 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 quite simple, however, still requires tons of focus. Malware can hide in various places, and it is far better to prevent it even before it goes into your PC than to trust in an anti-malware program. General cybersecurity knowledge is just an essential item in the modern world, even if your relationship with a computer stays on YouTube videos. That may keep you a lot of time and money which you would certainly spend while trying to find a fix guide.
