Krlock Virus – Details
The Krlock stands for a ransomware-type infection. The infection comes from the MedusaLocker ransomware family. Krlock was elaborated specifically to encrypt all major file types. Once the file is encrypted people are unable to use them. Krlock adds the “.krlock” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Krlock, will be renamed into “myphoto.jpg.krlock“. As soon as the encryption is completed, Krlock places a special text file into every folder containing the encrypted data.The message given by Krlock text file requesting for the ransom is absolutely the like the statements given by other ransomware virus representatives belonging to the MedusaLocker type. It literally mentions that the information is encrypted which the only way to restore it is to use a a special decryption key. Unfortunately, this is definitely true. The type of cryptography mechanism applied by Krlock is still not appropriately examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is completely unique. It is difficult to restore the files without the key available.
Another technique of Krlock is that the victims cannot access to the key. The key is kept on a specific server run by the frauds associated with Krlock ransomware. To get the key and recover the important information people have to pay the ransom.
Krlock encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.

Nevertheless, irrespective of the asked for amount, people must keep away from paying the virus. Cyber frauds are unfair, so they tend to entirely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive outcome and people just waste their money for absolutely nothing.
We strongly encourage that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Krlock ransomware and to recover the data data totally free. Therefore, the only best decision is to recover the lost data from the available backup.
