The virus has been making the rounds for about six weeks, causing a ransom notice to pop up on your screen threatening to hold your files hostage unless you pay to restore your files.
It could be related to the Cryptolocker virus that has some PC experts concerned.
With past viruses, often called ransomware, a trip to your local computer store and $100 got you back online with your files intact.
But the latest version, called a Cryptolocker, can permanently destroy every file, picture and email on your PC.
Ryan Malize, the owner of Pinellas Computers in Florida, says it's the nastiest virus he's seen. The Cryptolocker not only hijacks your computer and its files, it threatens to destroy them if the user doesn't come up with $300.
But that's not what makes this virus a killer.
It locks down your computer with a random password only the hacker knows. Experts like Malize can repair your computer, but may not be able to recover files as they are encrypted.
And there are no guarantees that paying the $300 ransom will lead to the restoration of your documents, pictures and anything else in your user folder including emails.
The virus hits your computer through links contained in emails and rogue websites. Here is how you can protect yourself:
1) Install or update antivirus software
2) Schedule back ups so if a virus does hit you don't lose everything.
3) Put children and others on limited user or guest accounts which helps to lock down your computer.
One of the best precautions you can take involves adjusting your pc's settings.
