There is a reason why specialists call '.dian File Extension' Ransomware the way they do – it appends a new filename extension .dian to users’ personal files thus encrypting them right after the successful entrance. Yes, this infection is one of those crypto-threats trying to obtain money from users by locking their videos, pictures, music, and other personal files.

No matter you decide to purchase the decryption tool or not, you cannot keep a ransomware infection active on your computer because it might encrypt even more files it finds stored on your system if you accidentally launch it again.
