How to remove Tastylock virus and restore encrypted files

Tastylock ransomware virus

Tastylock is the harmful software infecting PC's mainly through e-mail spam and Trojans. Sometimes hackers use zero-day vulnerabilities to get into the system, but they are speedily corrected. After penetration, the virus checks the hard disc, defines the amount of files for encryption and their general value. At the moment, each new virus knows how to cypher image, text, audio and video info in all most used formats. Virus encrypts all files, but the ones that might be business documents go first. All software on computer will be untouched because criminals are interested only in information. Encryption is carried out through famous AES and RSA algorithms, and its complexity is so high that it can't be bruteforced. This is the ground for unbelievable efficiency of this sort of viruses in last years: usual user, even having a fairly good knowledge of the PC, will never restore the files, and will be forced to pay the price. The single method to decrypt the data is to find the fraudster's website and get the master key. Some experienced hackers can get these keys due to flaws in viruse's program code. When encrypting files, Tastylock switches the extension of files to .Tastylock and adds _HELP_INSTRUCTION.txt file with next message

For all sorts of computer viruses, one thing is true: it's way easier to prevent it than to neutralize its consequences. For ransomware it's most relevant, as, unlike normal viruses, after uninstalling ransomware from the computer, the consequences of its actions will stay. To guard yourself, you have to remember these three basic principles:

    • Heed to the pop-ups. If the workstation is polluted by Tastylock, it will try to eliminate all copies of the data, to make the recovery less possible. The removal of shadow copies requires admin rights and verification from the user. The moment of thinking before confirming the dialogue box might save your files and your time.
    • Monitor the state of your workstation. File encrypting is a complicated operation that consumes a lot of system resources. If you notice a significant decrease in computer capacity or notice a unknown string in the Process Manager, you should switch off the PC, load it in safe mode, and scan for ransomware. These measures, in case of infection, will guard some of your files.
    • Be cautious with the messages that contain files. The #1 pattern of fraud letters is the story about prize gaining or package obtaining. The second most popular sort of fraud messages is a forgery for business correspondence. It is OK to be interested and click on the message even if it's sent to the incorrect address, but don't forget that one click on the viral file might cost you a lot of money, time and headache.
