How to remove PYSA ransomware and decrypt .pysa files

What is Pysa?

Recently, the new threat, called Pysa, has been detected. Its name the virus’s got due to the extension “.pysa”, that is added to encrypted files. Generally, this virus is distributed by the means of various executable files. They can be shared by various file sharing services and torrent trackers. Sometimes hackers even create websites that offer to download such a file, as if it’s something necessary for the system. Moreover, the code of the virus can be injected into a regular harmless file and be executed once a victim decides to open the file. If Pysa successfully got into the system, it changes some file folders and collects the information about a victim. When it’s done, it scans the hard drive and modifies the structures of suitable files. As the result, the files are unreadable and have the new “.pysa” extensions. Then the virus drops the ransom note, called “Readme.README.txt”. By the means of this note hackers try to force victims into purchasing the decryptor and, unfortunately, it’s the surest way to decrypt the data. However, they can easily deceive you: hackers often stop all contacts with their victims, once they’ve been paid or send a malicious software instead of the decryptor. That’s why we strongly recommend you not to contact with them and for this purpose we’ve prepared the detailed guide on how to remove PYSA ransomware and decrypt .pysa files.
