Cadq ransomware: Complete Uninstall Guide
Cadq ransomware is a hazardous PC threat designed by vicious cyber criminals with an aim to encrypt files and then extort huge amount of ransom from the victims for the decryption tool. This deadly crypto-malware uses a very strong encryption algorithm to lock the target files and can compromise almost all personal data including pictures, archives, documents, audios, videos etc. After that, those files become completely inaccessible for the users and can only be opened by using the proper decryption software which is allegedly kept on attackers’ server.
