Rozalocker Ransomware

Users who find that they cannot open their personal files out of the blue should check their systems because Rozalocker Ransomware could have sneaked onto their computers and encrypted their files already. The main symptom showing that this computer infection is responsible for locking all your files is the filename extension .enc added to all of them. Is it appended to those files you cannot access? If the answer is yes, the Russian ransomware infection Rozalocker Ransomware has, undoubtedly, found a way to enter your computer. Delete this file-encrypting threat as soon as possible and do not purchase the decryption key by any means even though it is said that it is your only chance to get important files back. Researchers at pcthreat.com are strictly against these payments to cyber criminals no matter that encrypted files are very important to users because, as their previous experience shows, crooks usually tell lies to users and do not send them the decryption key after receiving money. Evidently, their only purpose is to obtain money from users. No matter you are going to pay the ransom demanded by this computer infection or not, delete Rozalocker Ransomware without consideration because if you do not take care of it, it might strike again thus making your files unusable one more time.

You can be sure that Rozalocker Ransomware is inside your system if it is impossible to open personal files, they all have the .enc extension added next to their original extensions, and a new file ReadMe.txt can be found on Desktop. Users who cannot read in Russian will not understand what is written inside this file, which proves again that Rozalocker Ransomware is targeting Russian-speaking computer users. Let us help you. First of all, the message inside this file informs users that their files have been encrypted using a strong encryption algorithm. Second, they are told that they could unlock those files if they pay a ransom within 6 hours. At the time of writing, the size of the ransom is 10 000 Ruble, which equals $169. Users are told to send it in Bitcoins to the provided Bitcoin address. Purchasing the decryption key might be the only way to unlock those files, but our specialists do not encourage you to do that because there might be other ways to get those valuable files back. For example, users can recover the encrypted data from a backup they have created before the entrance of this file-encrypting threat. It would only be possible to do that if this backup is located on the other device, e.g. USB flash drive or a portable hard drive and, consequently, has not been affected by this ransomware infection. Try out all alternative data recovery methods before you go to transfer a ransom to crooks because it is very risky to give them what they want because they might have no motivation to send you the unlock key left after receiving your payment. In some cases, developers of ransomware do not even have the key for decrypting files stored anywhere, so they cannot give it to victims either.

We can say that Rozalocker Ransomware is distributed using illicit methods of distribution, but we should also note that users are the only ones who allow it to enter their PCs by opening attachments they find in spam emails they get. The opening of a malicious attachment immediately launches the ransomware infection, and it starts working actively on the computer. First of all, it changes the filename extensions of files thus encrypting them all. On top of that, it modifies the Hosts file by adding a bunch of popular Russian websites there so that users could not access any of them. You will need to fix it too after the deletion of Rozalocker Ransomware.

Luckily, Rozalocker Ransomware is not a very sophisticated ransomware-type infection, so users can disable it by finding and erasing the malicious file launched and deleting its ransom note left on the computer. As has already been mentioned, after doing that, you will need to go to fix the Hosts file too to be able to surf the web without any restrictions. Let our instructions help you, but if you are a busy person, we suggest using SpyHunter. It will remove the ransomware infection and then will fix the modified Hosts file for you promptly.
