How to decrypt files after Katyusha infection?
You may attempt to decrypt files infected by different versions of Katyusha manually. Modern ransomware threats use complex encryption algorithms and try to prevent users from decrypting their files by disabling System Restore option, removing Shadow copies and previous versions of user files. However, in most cases, there is still a chance to restore your files using one of the described metods. There is also special advanced data recovery software, that can revive lost data in several clicks. This is not a guarantee for data restoration, but it is worth giving a try.
Using advanced data recovery software
Restore encrypted files using System Restore
System Restore constantly creates copies of files and folders before major changes in the system (windows update, software installation). You can also create restore point manually from time to time. Katyusha may remove system restore files, but you can check it using following instruction.
Roll the files back to the previous version
Previous versions are copies of files and folders made by Windows Backup (if Windows Backup option is turned on) or copies of files and folders created by System Restore. You can use this feature to restore files and folders that you accidentally modified or deleted, or that were encypted by Katyusha. Available only in Windows 7 and later versions.
Restore files using shadow copies
Protect your computer from ransomware
Most of modern antivirus solutions have a module to protect from ransomware threats. However, there are also special solutions, that can detect cryptoviral activity and stop it, preventing modification of your files. One of the best is ZoneAlarm Anti-Ransomware utility, that will not use much resources for effective protection against latest ransomware threats.
