MSIL/Filecoder.ATX detection is a virus detection you can spectate in your computer. It generally appears after the preliminary procedures on your computer – opening the untrustworthy email, clicking the advertisement in the Web or installing the program from dubious sources. From the instance it appears, you have a short time to do something about it until it starts its malicious activity. And be sure – it is much better not to wait for these harmful things.

What is MSIL/Filecoder.ATX virus?

MSIL/Filecoder.ATX is ransomware-type malware. It searches for the documents on your disks, 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 changes the networking settings in order to avoid you from looking for the removal guides or downloading the anti-malware program. Sometimes, MSIL/Filecoder.ATX can even stop the launching of anti-malware programs.

MSIL/Filecoder.ATX Summary

In total, MSIL/Filecoder.ATX malware activities in the infected PC are next:

  • Authenticode signature is invalid;
  • Anomalous .NET characteristics;
  • CAPE detected the Chaos malware family;
  • Ciphering the files located on the victim’s disks — so the victim cannot use these files;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a major problem for the last 4 years. It is challenging to realize a more damaging malware for both individuals and companies. The algorithms used in MSIL/Filecoder.ATX (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy already exists, and possibly will exist. But that virus does not do all these unpleasant things without delay – it can require up to a few hours to cipher all of your documents. Hence, seeing the MSIL/Filecoder.ATX detection is a clear signal that you need to begin the removal procedure.

Where did I get the MSIL/Filecoder.ATX?

Common ways of MSIL/Filecoder.ATX injection are common for all other ransomware examples. Those are one-day landing sites where users are offered to download the free software, so-called bait e-mails and hacktools. Bait emails are a quite modern tactic in malware distribution – you receive the e-mail that imitates some routine notifications about shipments or bank service conditions updates. Inside of the email, there is an infected MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

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

Preventing it looks quite easy, however, still demands tons of focus. Malware can hide in various places, and it is far better to stop it even before it goes into your system than to trust in an anti-malware program. General cybersecurity awareness is just an essential thing in the modern world, even if your relationship with a PC stays on YouTube videos. That can save you a lot of money and time which you would spend while trying to find a solution.
