Virus.Virlock.04 detection is a virus detection you can spectate in your system. It usually shows up after the provoking procedures on your computer – opening the untrustworthy email, clicking the advertisement in the Web or mounting the program from untrustworthy sources.

What is Virus.Virlock.04 virus?

Virus.Virlock.04 is ransomware-type malware. It looks for the files on your computer, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files inaccessible, this malware also does a ton of harm to your system. It alters the networking setups in order to prevent you from checking out the removal guidelines or downloading the anti-malware program. In rare cases, Virus.Virlock.04 can additionally stop the launching of anti-malware programs.

Virus.Virlock.04 Summary

In summary, Virus.Virlock.04 ransomware actions in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • At least one process apparently crashed during execution;
  • Creates RWX memory;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Ciphering the files kept on the victim’s disk — so the victim cannot check these files;
  • Blocking the launching of .exe files of anti-virus apps
  • 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 hazardous malware for both individuals and organizations. The algorithms used in Virus.Virlock.04 (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 actually exists, and possibly will exist. But that virus does not do all these unpleasant things immediately – it can take up to several hours to cipher all of your documents. Thus, seeing the Virus.Virlock.04 detection is a clear signal that you need to start the clearing process.

Where did I get the Virus.Virlock.04?

Standard tactics of Virus.Virlock.04 injection are common for all other ransomware examples. Those are one-day landing web pages where users are offered to download the free app, so-called bait emails and hacktools. Bait emails are a quite new strategy in malware spreading – you receive the email that simulates some regular notifications about shippings or bank service conditions changes. Inside of the email, there is a malicious 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 pretty uncomplicated, however, still requires a lot of recognition. Malware can hide in various spots, and it is better to prevent it even before it goes into your computer than to rely upon an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern world, even if your interaction with a computer stays on YouTube videos. That may keep you a lot of money and time which you would certainly spend while trying to find a fix guide.
