Actually, Cerber ransomware is currently one of the most active threats spread around the Internet. Unfortunately, its strong 256-bit AES cipher is not decoded yet.
I totally go after Dino’s decision not to pay the ransom. What I know about dealing with ransomware infection is that you should enter the PC into Safe Mode. This step will isolate all files and objects associated with Cerber ransomware. Then you could completely remove Cerber ransomware from your system. Thus, will prevent encryption of other devices connected to the system.
The good news is you may have the chance to recover some of your data. One way you could try is with Shadow Explorer. In some cases the ransomware deletes shadow copies in Windows and this method may not work. Other method is using data recovery software. You could search the net and choose one. I’ve heard that some good alternative are Stellar Phoenix data recovery tool and File recover plus.
