The bug made its way onto thousands of computers across the world and changed the way people's computers communicated with the Internet, all in a ploy to steal personal information.
The FBI shut down the group behind the bug last November and changed out the group's servers with a clean server of their own.
But now that server is being taken off-line, too. When that happens, any computer with the malicious bug will be unable to communicate with the Internet.
The problem is easily detectable and the FBI has set up a website where you can easily tell if yours is affected.
If your computer fell victim to the Operation Ghost Click virus don't worry, the problems are repairable.
Computer technicians we spoke with Sunday say you should contact a trained professional to remove the virus and restore your computer.
They also say you should change any passwords for anything on your computer: Facebook, credit cards, even your wireless network passwords.
And if you were one of the lucky ones whose computer was not infected, don't get too comfortable. We're told the next big attack could be just around the corner.
Use this incident as a reminder to keep your anti-virus and malware software up to date, including the regular updates.
