|i wish i could format my harddrive.But i got many important files in my HDD..Windows reinstall korle hobe na?|
there is nothing to do with it maybe. because some days before I was infected also by this same kind of attack. I have searched a lot for finding a solution but I did not get a proper solution for backing up my files. so if you want to try then search its solution in google.
and one more thing, always keep turn on ransomware protection from your windows defender while you are using your pc.
