Tens of millions of U.S. computers are loaded with scam security software that their owners may have paid for but which only makes the machines more vulnerable, according to a new Symantec report on cybercrime.

The "alert" warns them of a virus and offers security software, sometimes for free and sometimes for a fee. "Lots of times, in fact they're a conduit for attackers to take over your machine. They'll take your credit card information, any personal information you've entered there and they've got your machine,"
