A new virus posing as an FBI alert is freezing computers and alarming users across the country. Infected computers display a shocking pop-up that tells owners they have illegal materials on their PCs and demands a $200 fine.
Computers infected with the FBI MoneyPak malware display a message using the FBI seal and citing several legal documents. It says "Your PC is blocked due to at least one of the reasons specified below." The reasons include owning and/or distributing copyrighted material, pornography or malware.
To unlock the computer, the virus demands a fine (amounts vary from $100 to $300) that must be paid with MoneyPak, a way to send cash without a bank account. It threatens criminal action against those who don't pay within three days.
