hackers have found a way to lock up the electronic documents on your computer and then demand a ransom for their return.

Security researchers at Websense, an internet security company based in San Diego, uncovered the unusual extortion plot when a corporate customer they would not identify fell victim to a virus that encrypted documents, photographs and spreadsheets. An e-mail was later sent demanding $200 for the digital keys to unlock the files.
