MSIL/TrojanDownloader.Agent.HAG detection is a malware detection you can spectate in your computer. It frequently appears after the preliminary activities on your computer – opening the suspicious email, clicking the banner in the Web or installing the program from suspicious resources. From the moment it appears, you have a short time to do something about it before it starts its malicious activity. And be sure – it is far better not to wait for these destructive actions.

What is MSIL/TrojanDownloader.Agent.HAG virus?

MSIL/TrojanDownloader.Agent.HAG is ransomware-type malware. It searches for the files on your disk, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents inaccessible, this virus also does a ton of harm to your system. It alters the networking setups in order to prevent you from looking for the removal guides or downloading the anti-malware program. In rare cases, MSIL/TrojanDownloader.Agent.HAG can also prevent the setup of anti-malware programs.

MSIL/TrojanDownloader.Agent.HAG Summary

Summarizingly, MSIL/TrojanDownloader.Agent.HAG virus activities in the infected system are next:

  • Dynamic (imported) function loading detected;
  • Authenticode signature is invalid;
  • Binary compilation timestomping detected;
  • Encrypting the files kept on the victim’s disk drives — so the victim cannot check 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 challenging to picture a more damaging malware for both individual users and corporations. The algorithms utilized in MSIL/TrojanDownloader.Agent.HAG (usually, 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 already exists, and possibly will exist. But that virus does not do all these bad things instantly – it may take up to several hours to cipher all of your files. Thus, seeing the MSIL/TrojanDownloader.Agent.HAG detection is a clear signal that you should begin the removal process.

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

General tactics of MSIL/TrojanDownloader.Agent.HAG spreading are usual for all other ransomware variants. Those are one-day landing web pages where victims are offered to download and install the free software, so-called bait emails and hacktools. Bait e-mails are a pretty new tactic 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 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 pretty uncomplicated, but still demands tons of attention. Malware can hide in different places, and it is far better to prevent it even before it gets into your system than to rely upon an anti-malware program. General cybersecurity knowledge is just an important item in the modern world, even if your relationship with a PC stays on YouTube videos. That can save you a lot of time and money which you would spend while trying to find a fixing guide.
