Lower-right part of screen is a small popup window: "Antivirus software alert. INFILTRATION ALERT: Your computer is being attacked by an Internet Virus. It could be a password-stealing attack, a trojan - dropper or similar. DETAILS: [...] Do you want to block the attack?"
I also get intermittent popups of IE windows to websites that I most definitely have not been to before!!
There are also about fifty little red shields in my icon tray, so many that they obscure the other icons and the time.
HOWEVER, if I start in Safe Mode, run MSCONFIG.EXE and click "Selective Startup," unclick "Load Startup Items," and restart, then the bad stuff does not load.
Edited to Add: I guess I should add that I'm using Windows XP Professional SP 2
