What is MSIL/TrojanDropper.Agent.ESS virus?

MSIL/TrojanDropper.Agent.ESS is ransomware-type malware. It looks for the files on your computer, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files locked, this virus also does a ton of damage to your system.

In some cases, MSIL/TrojanDropper.Agent.ESS can also stop the setup of anti-malware programs.

MSIL/TrojanDropper.Agent.ESS Summary

Summarizingly, MSIL/TrojanDropper.Agent.ESS virus actions in the infected computer are next:

  • Authenticode signature is invalid;
  • Anomalous .NET characteristics;
  • Ciphering the files kept on the victim’s drive — so the victim cannot check these documents;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of anti-malware apps

Ransomware has actually been a nightmare for the last 4 years. It is challenging to realize a more hazardous malware for both individuals and organizations. The algorithms utilized in MSIL/TrojanDropper.Agent.ESS (typically, 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 actually exists, and possibly will exist. However, that virus does not do all these horrible things without delay – it can take up to several hours to cipher all of your documents. Hence, seeing the MSIL/TrojanDropper.Agent.ESS detection is a clear signal that you have to start the elimination procedure.

Where did I get the MSIL/TrojanDropper.Agent.ESS?

Ordinary tactics of MSIL/TrojanDropper.Agent.ESS spreading are usual for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free software, so-called bait emails and hacktools. Bait emails are a relatively new method in malware spreading – you get the e-mail that simulates some normal notifications about shipments or bank service conditions shifts. Within the e-mail, there is an infected MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

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

Avoiding it looks quite easy, however, still requires tons of attention. Malware can hide in different places, and it is much better to stop it even before it gets into your PC than to depend on an anti-malware program. Standard cybersecurity awareness is just an essential thing in the modern-day world, even if your relationship with a computer remains on YouTube videos. That may keep you a lot of time and money which you would spend while looking for a fix guide.
