It's nine o'clock... Do you know who is using your computer?

It's nine o'clock... Do you know who is using your computer? Tens of thousands of consumers are unwitting accomplices of illegal spammers and at the mercy of identity thieves, warns the Federal Trade Commission. These consumers' computers have been secretly hijacked by criminals who install spam-sending software and spyware on the computers when consumers open malicious e-mail attachments or visit a malicious Web site. After gaining access to consumers' computers, the criminals can track consumers' Internet surfing, steal personal information, and turn the computers into spam "zombies" that are part of a "botnet" made up of thousands of home computers through which spammers route spam.
