MSIL/TrojanDownloader.Agent.PCL detection is a virus detection you can spectate in your system. It often shows up after the preliminary actions on your PC – opening the dubious email messages, clicking the banner in the Internet or mounting the program from dubious resources. From the second it shows up, you have a short time to do something about it until it begins its harmful activity. And be sure – it is much better not to await these harmful effects.

What is MSIL/TrojanDownloader.Agent.PCL virus?

MSIL/TrojanDownloader.Agent.PCL is ransomware-type malware. It looks for the files on your disk, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your files locked, this virus also does a lot of damage to your system. It changes the networking settings in order to avoid you from reading the removal tutorials or downloading the anti-malware program. In some cases, MSIL/TrojanDownloader.Agent.PCL can also block the setup of anti-malware programs.

MSIL/TrojanDownloader.Agent.PCL Summary

Summarizingly, MSIL/TrojanDownloader.Agent.PCL ransomware actions in the infected computer are next:

  • CAPE extracted potentially suspicious content;
  • .NET file is packed/obfuscated with SmartAssembly;
  • Authenticode signature is invalid;
  • Encrypting the files located on the target’s drive — so the victim cannot use these files;
  • Blocking the launching of .exe files of anti-virus programs
  • Blocking the launching of installation files of security tools

Ransomware has been a horror story for the last 4 years. It is hard to imagine a more dangerous malware for both individual users and businesses. The algorithms used in MSIL/TrojanDownloader.Agent.PCL (generally, 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 currently exists, and possibly will exist. However, that malware does not do all these horrible things instantly – it may take up to a few hours to cipher all of your documents. Hence, seeing the MSIL/TrojanDownloader.Agent.PCL detection is a clear signal that you need to begin the elimination procedure.

Where did I get the MSIL/TrojanDownloader.Agent.PCL?

Usual tactics of MSIL/TrojanDownloader.Agent.PCL injection are basic for all other ransomware examples. Those are one-day landing websites where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait e-mails are a pretty new method in malware spreading – you receive the email that imitates some routine notifications about shipments or bank service conditions shifts. Within the e-mail, there is a malicious 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.

Preventing it looks pretty simple, however, still demands a lot of recognition. Malware can hide in different places, and it is much better to stop it even before it invades your system than to rely upon an anti-malware program. Basic cybersecurity awareness is just an essential item in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may save you a lot of time and money which you would spend while seeking a solution.
