Solved Answer

Ykcol file extension virus (also known as Ykcol ransomware) is a variant of Locky crypto-malware that encodes victim’s files for ransom. The malicious virus is actively distributed by Necurs botnet spam that delivers deceptive email attachments containing a JavaScript file inside of .7z attachment.

As soon as the .js file is opened, the script inside of it will address a web page hosting Ykcol ransomware and download a malicious program from there. Soon after, the script executes the fresh sample of Ykcol and allows it to encrypt all files on the system. The ransomware leaves instructions in ykcol.bmp and ykcol.htm files.

The virus points the victim to a website that can be accessed via Tor browser only. Here, the ransom price is stated. The new Locky variant asks from 0.25 to 0.4 Bitcoin as a ransom, whereas earlier it never lowered the price below half a Bitcoin.

Security experts say that paying the ransom is not a solution to the problem and it does not necessarily help to recover encrypted files. There are tons of other reasons why you shouldn't pay cyber extortionists, too. First of all, you risk losing a great amount of money and second, you fund criminals' projects and motivate them to continue working on future ransomware projects.

Unfortunately, Locky virus is extremely sophisticated and advanced piece of malware and reversing the damage it inflicts is simply not that easy. However, there are some methods you can try to recover .yckol file extension files.
