A nationwide inspection indicates Internet users at home are not nearly as safe online as they believe.
The inspections found most consumers have no firewall protection, outdated antivirus software and dozens of spyware programs secretly running on their computers.
The study from America Online and the National Cyber Security Alliance finds 77 percent of those questioned say they're safe from online threats.
But when experts visited those same homes to examine computers, they found two-thirds had no protective firewall program and 80-percent had spyware.
One Virginia man says he was "blown away" to learn his three-year-old computer was infected with viruses and had more than 600 pieces of spyware monitoring his online activities.
