Windows 7 'compatibility checker' is a Trojan
Scammers are infecting computers with a Trojan horse program disguised as software that determines whether PCs are compatible with Windows 7.
The attack was first spotted by BitDefender on Sunday and is not yet widespread; the antivirus vendor is receiving reports of about three installs per hour from its users in the U.S. But because the scam is novel, it could end up infecting a lot of people, according to Catalin Cosoi, the head of BitDefender's Online Threats Lab. "This actually works because of the interest in Windows 7," he said.
