My good friend Dave Dockery of Synergy Publishing has put together a nice seminar on cleaning PC's infected with spyware and other unwanted pieces of software.
He gives his Defending Your Computer seminar all over the West Coast of Florida, often at meetings of the Tampa Bay Computer Society.
Doc and I disagree on somethings, like I'd put installing Service Pack 2 as the first thing anyone should do, but he's a great speaker and a accomplished educator.
