How to remove TeslaWare virus and restore encrypted files

By itself ransomware is a separate type of virus, which, in turn, is divided into several subspecies due to their complexity. The most complex are viruses, which are created by teams of experienced hackers in order to obtain large profits, such as WanaCry, CERBER, Locky and so on. They are followed by medium-complexity ransomware, which manage to earn several thousand dollars to their creators, and are hacked by IT-laboratories within a week. At the very bottom are viruses that are created for sale, and their creators do not even try to use these viruses for earnings - they only sell them at auctions in the Dark Web. Anyone can buy such virus and there can be quite a lot of reasons to do it: beginning from the banal desire to earn and ending with revenge someone, or the desire to harm a particular person or company by running a virus into its network. TeslaWare belongs to the category of third-rate viruses, and it can be purchased at an illegal auction for a price of $40 to $70. It is the exact price that the creators of the virus evaluate the fruits of their labors, although leading malware analysts believe that the virus does not cost even such money, because its code is full of errors and vulnerabilities that can be easily used to decrypt files.

 

TeslaWare ransomware virus

 

At the moment the virus uses the AES-256 encryption algorithm, assigns the .tesla extension to the encrypted files, and puts Nikola Tesla's photo as desktop wallpaper. In addition, the virus threatens the user with data deletion. This happens according to simple scheme: every hour the program selects ten random files and deletes them. If the ransom is not paid within 72 hours, then all files are deleted without the possibility of recovery. Unfortunately, this statement is true, and the virus can actually remove the files, but now there are ways to decrypt data before deletion, which you can familiarize with in a special topic on the forum www.bleepingcomputer.com.

How to delete TeslaWare Virus

File recovery is the first task, which you worry about, when your PC is infected by TeslaWare. Still, the virus should be deleted in order to shield new files. Regardless of which recovery way you will use, you still have to eliminate ransomware. The instant uninstall is needful if you prefer the manual decryption, or you are going to load the backups, and if you decide to pay the ransom - the virus should be removed after the complete file decryption. The removal can be performed with help of special antivirus program, or manually. Security and swiftness of both methods are the same, but the requirements for user experience and skill are extremely different. You have to be an experienced PC operator to perform the manual deletion with no errors. You must know what to do and how to prevent any error.
