MSIL/Filecoder.AQQ detection is a virus detection you can spectate in your computer. It usually shows up after the provoking activities on your PC – opening the suspicious email messages, clicking the advertisement in the Web or installing the program from untrustworthy resources. From the moment it appears, you have a short time to take action until it starts its destructive action. And be sure – it is far better not to wait for these harmful effects.

What is MSIL/Filecoder.AQQ virus?

MSIL/Filecoder.AQQ is ransomware-type malware. It searches for the files on your disk, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this virus also does a ton of harm to your system. It alters the networking settings in order to prevent you from reading the elimination articles or downloading the antivirus. Sometimes, MSIL/Filecoder.AQQ can also prevent the launching of anti-malware programs.

MSIL/Filecoder.AQQ Summary

In total, MSIL/Filecoder.AQQ malware actions in the infected system are next:

  • Dynamic (imported) function loading detected;
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Binary compilation timestomping detected;
  • Encrypting the files located on the victim’s drive — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a horror story for the last 4 years. It is hard to realize a more dangerous virus for both individual users and organizations. The algorithms used in MSIL/Filecoder.AQQ (typically, 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. But that malware does not do all these horrible things immediately – it can take up to several hours to cipher all of your files. Hence, seeing the MSIL/Filecoder.AQQ detection is a clear signal that you need to begin the clearing procedure.

Where did I get the MSIL/Filecoder.AQQ?

Standard methods of MSIL/Filecoder.AQQ distribution are standard for all other ransomware examples. Those are one-day landing sites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a pretty new strategy in malware distribution – you receive the e-mail that imitates some routine notifications about shippings or bank service conditions shifts. Inside of the e-mail, there is a corrupted 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 requires a lot of attention. Malware can hide in different places, and it is better to prevent it even before it goes into your computer than to rely on an anti-malware program. Basic cybersecurity awareness is just an important thing in the modern-day world, even if your relationship with a computer stays on YouTube videos. That may save you a great deal of money and time which you would certainly spend while searching for a solution.
