MSIL/Agent.TBG detection is a malware detection you can spectate in your system. It frequently shows up after the preliminary procedures on your computer – opening the suspicious e-mail messages, clicking the advertisement in the Internet or mounting the program from unreliable resources. From the instance it shows up, you have a short time to do something about it before it starts its malicious activity. And be sure – it is much better not to wait for these malicious things.

What is MSIL/Agent.TBG virus?

MSIL/Agent.TBG is ransomware-type malware. It looks for the files on your computer, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your documents inaccessible, this malware also does a ton of damage to your system. It modifies the networking setups in order to avoid you from reading the elimination tutorials or downloading the anti-malware program. In some cases, MSIL/Agent.TBG can even block the launching of anti-malware programs.

MSIL/Agent.TBG Summary

Summarizingly, MSIL/Agent.TBG malware activities in the infected PC are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Dynamic (imported) function loading detected;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Possible date expiration check, exits too soon after checking local time;
  • Enumerates the modules from a process (may be used to locate base addresses in process injection);
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • CAPE detected the RedLine malware family;
  • Anomalous binary characteristics;
  • Ciphering the files located on the target’s disk — so the victim cannot use these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of security tools

Ransomware has been a headache for the last 4 years. It is challenging to imagine a more damaging malware for both individuals and corporations. The algorithms used in MSIL/Agent.TBG (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 currently exists, and possibly will exist. But that virus does not do all these horrible things without delay – it may require up to a few hours to cipher all of your files. Therefore, seeing the MSIL/Agent.TBG detection is a clear signal that you must start the elimination procedure.

Where did I get the MSIL/Agent.TBG?

Typical ways of MSIL/Agent.TBG spreading are usual for all other ransomware examples. Those are one-day landing websites where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a quite modern tactic in malware spreading – you get the e-mail that mimics some regular notifications about deliveries or bank service conditions modifications. Inside of the email, there is an infected MS Office file, or a web 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 quite uncomplicated, but still demands a lot of recognition. Malware can hide in different spots, and it is far better to prevent it even before it gets into your computer than to rely upon an anti-malware program. Basic cybersecurity awareness is just an important thing in the modern 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 fixing guide.
