Virus.VirLock.1 detection is a virus detection you can spectate in your computer. It usually shows up after the preliminary procedures on your PC – opening the untrustworthy email messages, clicking the advertisement in the Web or installing the program from suspicious sources. From the moment it appears, you have a short time to act before it starts its harmful action. And be sure – it is much better not to wait for these malicious things.

What is Virus.VirLock.1 virus?

Virus.VirLock.1 is ransomware-type malware. It looks for the files on your disk, encrypts it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this virus additionally does a ton of damage to your system. It changes the networking settings in order to stop you from looking for the removal tutorials or downloading the antivirus. Sometimes, Virus.VirLock.1 can also block the launching of anti-malware programs.

Virus.VirLock.1 Summary

In summary, Virus.VirLock.1 virus activities in the infected computer 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;
  • Encrypting the documents kept on the victim’s disks — so the victim cannot check these files;
  • 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 difficult to realize a more hazardous malware for both individual users and companies. The algorithms used in Virus.VirLock.1 (usually, 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 currently exists, and possibly will exist. However, that malware does not do all these unpleasant things immediately – it can require up to several hours to cipher all of your files. Thus, seeing the Virus.VirLock.1 detection is a clear signal that you should begin the clearing process.

Where did I get the Virus.VirLock.1?

Ordinary tactics of Virus.VirLock.1 injection are typical for all other ransomware examples. Those are one-day landing sites where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a quite new method in malware spreading – you get the e-mail that mimics some regular notifications about shippings or bank service conditions shifts. Inside of the email, there is a corrupted 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.

Avoiding it looks fairly simple, but still demands tons of awareness. Malware can hide in different spots, and it is much better to stop it even before it goes into your system than to trust in an anti-malware program. Common cybersecurity awareness is just an essential thing in the modern world, even if your interaction with a computer remains on YouTube videos. That may keep you a great deal of money and time which you would spend while looking for a solution.
