What is Malware.Heuristic.2091 virus?

Malware.Heuristic.2091 is ransomware-type malware. It looks for the files on your disk drives, ciphers it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents locked, this virus additionally does a ton of damage to your system. It alters the networking setups in order to stop you from checking out the elimination tutorials or downloading the anti-malware program. Sometimes, Malware.Heuristic.2091 can even block the launching of anti-malware programs.

Malware.Heuristic.2091 Summary

In summary, Malware.Heuristic.2091 ransomware actions in the infected system are next:

  • The binary contains an unknown PE section name indicative of packing;
  • The binary likely contains encrypted or compressed data.;
  • The executable is likely packed with VMProtect;
  • Authenticode signature is invalid;
  • Binary file triggered YARA rule;
  • Yara detections observed in process dumps, payloads or dropped files;
  • Ciphering the documents kept on the target’s disks — so the victim cannot open these documents;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware programs

Ransomware has actually been a horror story for the last 4 years. It is challenging to imagine a more hazardous virus for both individuals and businesses. The algorithms used in Malware.Heuristic.2091 (typically, 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 actually exists, and possibly will exist. But that virus does not do all these terrible things immediately – it can require up to a few hours to cipher all of your files. Therefore, seeing the Malware.Heuristic.2091 detection is a clear signal that you have to start the removal process.

Where did I get the Malware.Heuristic.2091?

Ordinary ways of Malware.Heuristic.2091 injection are basic for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a relatively modern method in malware distribution – you get the e-mail that imitates some regular notifications about deliveries or bank service conditions updates. Inside of the e-mail, there is an infected MS Office file, or a 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 fairly easy, but still requires tons of awareness. Malware can hide in various places, and it is far better to stop it even before it goes into your PC than to depend on an anti-malware program. Simple cybersecurity awareness is just an important thing in the modern world, even if your interaction with a PC stays on YouTube videos. That can save you a lot of money and time which you would spend while searching for a solution.
