It usually shows up after the preliminary actions on your computer – opening the suspicious email, clicking the advertisement in the Internet or installing the program from dubious resources.

What is Sf:VirLock-A virus?

Sf:VirLock-A is ransomware-type malware. It searches for the files on your disks, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your documents locked, this malware additionally does a lot of damage to your system.

In some cases, Sf:VirLock-A can also prevent the launching of anti-malware programs.

Sf:VirLock-A Summary

Summarizingly, Sf:VirLock-A virus actions in the infected system are next:

  • Sample contains Overlay data;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Anomalous binary characteristics;
  • Encrypting the documents kept on the target’s disk — 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 programs

Ransomware has actually been a horror story for the last 4 years. It is challenging to imagine a more harmful virus for both individual users and businesses. The algorithms utilized in Sf:VirLock-A (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 currently exists, and possibly will exist. However, that virus does not do all these horrible things without delay – it can require up to a few hours to cipher all of your documents. Hence, seeing the Sf:VirLock-A detection is a clear signal that you need to begin the clearing process.

Where did I get the Sf:VirLock-A?

Typical methods of Sf:VirLock-A injection are typical for all other ransomware examples. Those are one-day landing web pages where users are offered to download and install the free software, so-called bait emails and hacktools. Bait e-mails are a relatively new method in malware spreading – you receive the e-mail that simulates some normal notifications about shippings or bank service conditions updates. Inside of the email, there is a corrupted MS Office file, or a 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 uncomplicated, however, still needs tons of awareness. Malware can hide in different spots, and it is much better to stop it even before it gets into your PC than to depend on an anti-malware program. Essential 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 save you a lot of time and money which you would certainly spend while searching for a solution.
