Remove Kovasoh Virus Ransomware (+.Kovasoh File Recovery)

.Lotej File

Through the use of Ransomware, the hackers of the Internet are able to make the files of their victims inaccessible to anyone who may try to open them. The method which allows Ransomware infections to achieve this is called data-encryption. In and of itself, the data-encryption method isn’t something that’s harmful or damaging. In fact, it is supposed to keep files safe from unauthorized access and modifications. It is oftentimes used by people who wish to keep some very important data safe and secure. However, when this method is implemented by cyber criminals who create Ransomware threats, the whole effect of the data-encryption gets reversed, and used for the purposes of illegal money extortion. The gist of the Ransomware scheme is that, once the user gets their data encrypted, their only hope of restoring the files would be through the payment of a ransom.

The new .Kovasoh virus

.Kovasoh Virus
After the ransomware is done encrypting your files, it will leave a _readme.txt file with instructions.

 Kovasoh is a cryptovirus infection that works in this exact way – it uses its advanced data encryption to render the files of its targets inaccessible and then it shows a notification banner on the computer screen. Through the message in this banner, the user learns that their files have been locked by a Ransomware and that they would need to pay money to the hackers if they are to acquire the decryption key corresponding to the encryption code. Many users pay the demanded ransom immediately after they read the ransom message. However, a lot of people can’t afford to spend a couple of hundred, or even a couple of thousand dollars by sending them to some online criminals. Also, and this should go without saying, there isn’t any conceivable way of actually knowing whether or not the hackers would enable you to restore the access to your data by sending you the corresponding decryption key – for all you know, they may simply be lying to you. And of course, should you still send your money to the criminals behind an infection such as Kovasoh,  CosakosNvetud you’d never get the chance to get that money back from the hackers. Even if you don’t get to unlock your files after the payment, there wouldn’t be a refund.
