What is Cerber
Cerber is ransomware virus that uses AES encryption to encrypt user files. Usually it affects documents, photos, images, music, games and other types of personal data. Cerber adds .cerber extension to all encrypted files. Targeting personal information helps them to demand ransom ($500) for decryption. As there are no 100% working free decryption tools available many users pay the ransom to restore their files. After 7 days amount of ransom doubles. Cerber ransomware creates 3 files (#DECRYPT MY FILES#.txt, #DECRYPT MY FILES#.html, #DECRYPT MY FILES#.vbs) that contain instructions and link to online “Cerber Decryptor”. In this article we will explain how to remove Cerber virus and decrypt .cerber files.
How Cerber infected your PC
Cerber virus developers use spam e-mail attachments for distribution. Usually short message offers to download archive with some document. This document contains built-in macros, that runs in the background when user opens the document. This macros downloads executable file of the virus and runs it. Since that moment Cerber starts encrypting your files. Antivirus may not catch this threat and we recommend you to use HitmanPro with Cryptoguard. This program can detect encryption process and stop it to prevent the loss of your files.
