It usually appears after the preliminary actions on your computer – opening the untrustworthy email messages, clicking the banner in the Internet or setting up the program from untrustworthy sources.

What is MSIL/Shutdowner.CA virus?

MSIL/Shutdowner.CA is ransomware-type malware. It looks for the files on your disk drive, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware additionally does a lot of damage to your system. It changes the networking settings in order to prevent you from checking out the removal manuals or downloading the anti-malware program. Sometimes, MSIL/Shutdowner.CA can even stop the setup of anti-malware programs.

MSIL/Shutdowner.CA Summary

In summary, MSIL/Shutdowner.CA ransomware activities in the infected PC are next:

  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Encrypting the files kept on the target’s drives — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-virus apps

Ransomware has actually been a headache for the last 4 years. It is hard to picture a more damaging malware for both individuals and corporations. The algorithms used in MSIL/Shutdowner.CA (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these unpleasant things without delay – it may require up to several hours to cipher all of your files. Therefore, seeing the MSIL/Shutdowner.CA detection is a clear signal that you must start the removal process.

Where did I get the MSIL/Shutdowner.CA?

Common tactics of MSIL/Shutdowner.CA distribution are standard for all other ransomware examples. Those are one-day landing web pages where users are offered to download and install the free app, so-called bait e-mails and hacktools. Bait e-mails are a quite modern tactic in malware distribution – you get the e-mail that simulates some routine notifications about shippings or bank service conditions shifts. Inside of the e-mail, there is an infected MS Office file, or a 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 fairly uncomplicated, but still requires tons of focus. Malware can hide in various places, and it is better to prevent it even before it goes into your computer than to depend on an anti-malware program. Standard cybersecurity knowledge is just an essential item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That can keep you a great deal of money and time which you would certainly spend while trying to find a solution.
