MSIL/Agent.UAT detection is a malware detection you can spectate in your system. It frequently shows up after the preliminary activities on your computer – opening the untrustworthy email messages, clicking the banner in the Internet or installing the program from suspicious resources. From the instance it shows up, you have a short time to act before it starts its harmful activity. And be sure – it is better not to await these destructive actions.

What is MSIL/Agent.UAT virus?

MSIL/Agent.UAT is ransomware-type malware. It looks for the documents on your computer, ciphers it, and after that 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 modifies the networking settings in order to prevent you from reading the removal tutorials or downloading the anti-malware program. Sometimes, MSIL/Agent.UAT can also stop the launching of anti-malware programs.

MSIL/Agent.UAT Summary

In summary, MSIL/Agent.UAT virus actions in the infected PC are next:

  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Ciphering the documents kept on the target’s drives — so the victim cannot open these files;
  • Blocking the launching of .exe files of anti-virus programs
  • Blocking the launching of installation files of anti-virus programs

Ransomware has actually been a nightmare for the last 4 years. It is difficult to realize a more hazardous virus for both individuals and businesses. The algorithms used in MSIL/Agent.UAT (usually, 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. However, that virus does not do all these horrible things instantly – it may require up to several hours to cipher all of your documents. Thus, seeing the MSIL/Agent.UAT detection is a clear signal that you must start the clearing procedure.

Where did I get the MSIL/Agent.UAT?

Typical ways of MSIL/Agent.UAT distribution are common for all other ransomware examples. Those are one-day landing websites where users are offered to download the free software, so-called bait emails and hacktools. Bait e-mails are a relatively new method in malware spreading – you get the e-mail that simulates some regular notifications about deliveries or bank service conditions changes. Inside of the email, there is a malicious 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 quite easy, but still needs tons of attention. Malware can hide in various places, and it is far better to prevent it even before it invades your PC than to rely upon an anti-malware program. Standard cybersecurity awareness is just an essential item in the modern-day world, even if your interaction with a computer stays on YouTube videos. That may save you a great deal of time and money which you would spend while seeking a fix guide.
