The people over at F-Secure have analyzed the latest in “Ransomware” (viruses which encrypt your data and charge you a “fee” to unlock it). In the end, they came up with a pretty profound solution to this problem—ok, it’s not profound, it’s something you should be doing anyhow.
Their opinion is this. If you are following a good backup strategy, and are infected with one of these worms, you have two choices 1) pay the money (which is a bad idea) or 2) delete the file and restore it from a backup.
Online backups services like Carbonite, Mozy, iDrive, Dropbox, and Amazon S3 (to name a few) may cost you more than the "Ransom", but in the end knowing that your data is safe—be it virus, fire, flood, or 2012, it’s worth the money.
Have a great day:)
