Would you like to learn how to remove the Lokf Virus infection from your system? We can assist you to do that right here. If you’ve become a victim of this extremely harmful file-encrypting Ransomware, you’ll find the exact steps on how to get rid of it successfully in the next lines. Not only that, but you may also get some ideas on how to restore your encrypted files without paying the ransom with the help of the instructions below. But let’s first say a few words about the exact malware piece you are facing, and the possible ways to deal with it.

What Is Lokf Virus?

Lokf Virus works is very different from the way any other type of malware functions. Most viruses and malware programs attempt to cause some system damage, collect credentials, spy on you, or steal some sensitive information that can later be used for cyber crimes. Lokf Virus, on the other hand, uses a unique technique called file-encryption that does not ruin your system or files, but instead simply locks the data with a powerful algorithm. Once the Ransomware finds its way to your machine, it quietly activates a file-encryption process in the background of the system. As a result, all the files stored on the computer become unreadable and, cannot be opened or used without the application of a special decryption key. 

Upon the completion of the encryption process, the malware reveals itself with a ransom note that gets directly on the victim’s screen. This note contains a message from the cyber criminals who control the infection. They inform you that your files have been locked with secret encryption, and the only way you can access them is by paying a ransom in exchange for the decryption key they possess. The payment is typically requested in Bitcoins as, for cyber-thefts, this is a very convenient money transaction method, because this online currency is untraceable, and helps them to remain hidden from the authorities. The crooks provide all the payment instructions to the victims, and often give a short deadline. If the payment is not made within the set deadline, however, the hackers oftentimes threaten to double the ransom amount, or even destroy the unique decryption key, capable of recovering your encrypted data.

The Lokf Virus file encryption

Unfortunately, there’s not much you can do when you fall a victim to a Ransomware like Lokf Virus, Coot or Mosk. There are basically two possible choices – pay the ransom, and leave yourself at the mercy of the crooks, or remove the infection by yourself, and try to get your files back via other means. The unscrupulous crooks are not afraid to use various manipulative approaches to press the victims into paying the ransom. However, abiding the hackers’ demands does not guarantee that the victims would actually get a working decryption key. At the same time, the infected machine remains vulnerable to all kinds of malicious threats and attacks, while the Ransomware is present on it.

That’s why cleaning your system from Lokf Virus is a good way to block the hacker’s access to your computer. You can do this if you follow the instructions below. We also recommend that you have a look at our file-recovery suggestions that are included in the guide. You may potentially find a solution for decrypting your files there. We should inform you, though, that the developers of Ransomware are one step ahead of the security researchers. Therefore, some encryption algorithms of Ransomware are more challenging to decrypt than others. Regardless, regaining control over your computer and not paying a penny to the unscrupulous cyber-criminals is still the preferable option.
