This nasty new malware isn’t like anything we’ve ever dealt with. It encrypts your personal files and the only way to rescue them is to pay the ransom. The infection can be removed but the files can only be decrypted with a key – the criminals are the only ones that have the key and they only give you 100 hours to pay. It is very important that you back up your files on something other than your hard drive (dvd, cd, thumb drive, etc.)
