Articles about removing ransomware that blocks Windows or browsers and can encrypt your data and demand ransom.
UltraCrypter is updated version of previously described CryptXXX virus, that can be called CryptXXX 3.0 ransomware. Malware developers made some crucial changes, that are not very pleasant for potential victims. It still uses AES CBC 256-bit encryption algorithm, but now it adds .cryp1 extension to encrypted files. Ransom is 1.2 Bitcoins (around 500$). Bad news are, that now decryptors for CryptXXX does not work. That means the only chance to decrypt UltraCrypter-affected files is if you have external backup or enabled Windows service that will store previous versions of your files.
