In the past month, several antivirus companies have discovered a new ransomware variant known as Cryptolocker. Ransomware is a type of malware on the rise that holds your precious files hostage for money.
It does that by searching your computer and shares for popular file extensions and encrypts them preventing you from accessing them ever again unless you pay up.
This type of ransomware does not spread to other PCs or replicate by itself. This program needs your interaction to do its evil work. Ransomware needs you to launch the program on your PC. Of course, like phishing scams, It does this by trying to trick you into opening up some random attachment from a random email.
This attachment (could be a picture, zip file or other) contains the simple script to get it started doing its havoc on your PC.
If your PC gets infected then your files will more then likely be encrypted shortly after and will not be able to access them. It is impossible to decrypt the files without the private key.
