What is Cryptolocker or Ransomware?

Cryptolocker or Ransomware is a piece of code, if run, will search all your drives for documents, spreadsheets, pdf files etc and encrypt them with an encryption key.

After encryption it will usually rename the files as filename.encrypted. This code will encrypt files even on mapped drives to servers, so backups are essential. You will either have to restore from backup or pay the people who have encrypted your files for them to send you the decryption key. This usually costs around the $1000 mark and payment is usually required with Bitcoins, an internet currency.
