You don't have kids who get on the computer and install spyware every time you turn your back. But innoculating with Spybot, Spyware Blaster, and Spyware Guard have blocked most of it. When they go to reinstall Kazaa or the latest thing their friends have told them about, my computer won't let them do it.
That's true. I'm the only user on this computer and I'm very careful. I've clicked on a couple of buttons on websites and had the blocker pop up. Never, ever override it! That's the clue. I hit the major news sites and Drudge and FR daily. I shop online. Never had a problem.
