Ransom:Win32/FileCoder.GJN!MTB detection is a virus detection you can spectate in your system. It usually shows up after the provoking activities on your PC – opening the dubious email messages, clicking the banner in the Internet or mounting the program from suspicious resources. From the second it shows up, you have a short time to do something about it until it begins its harmful action. And be sure – it is far better not to wait for these malicious effects.

What is Ransom:Win32/FileCoder.GJN!MTB virus?

Ransom:Win32/FileCoder.GJN!MTB is ransomware-type malware. It looks for the documents on your computer, ciphers it, and then asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this virus also does a lot of damage to your system. It alters the networking setups in order to avoid you from looking for the elimination articles or downloading the anti-malware program. In rare cases, Ransom:Win32/FileCoder.GJN!MTB can also prevent the launching of anti-malware programs.

Ransom:Win32/FileCoder.GJN!MTB Summary

Summarizingly, Ransom:Win32/FileCoder.GJN!MTB virus activities in the infected computer are next:

  • Uses Windows utilities for basic functionality;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Encrypting the files kept on the victim’s disks — so the victim cannot open these files;
  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a nightmare for the last 4 years. It is difficult to realize a more damaging malware for both individuals and organizations. The algorithms used in Ransom:Win32/FileCoder.GJN!MTB (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy actually exists, and possibly will exist. However, that malware does not do all these horrible things immediately – it can take up to a few hours to cipher all of your documents. Therefore, seeing the Ransom:Win32/FileCoder.GJN!MTB detection is a clear signal that you should start the elimination procedure.

Where did I get the Ransom:Win32/FileCoder.GJN!MTB?

Standard tactics of Ransom:Win32/FileCoder.GJN!MTB spreading are common for all other ransomware examples. Those are one-day landing sites where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait e-mails are a quite modern method in malware distribution – you get the email that imitates some standard notifications about shipments or bank service conditions changes. Inside of the e-mail, 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, but still demands tons of focus. Malware can hide in various places, and it is much better to stop it even before it goes into your PC than to depend on an anti-malware program. General cybersecurity knowledge is just an important thing in the modern world, even if your interaction with a computer stays on YouTube videos. That may keep you a great deal of money and time which you would spend while searching for a solution.
