sorry to burst your bubble dude but there's no such thing as an html virus.

If you have windows 2000/xp then run task manager and see what processes are running, you might be able to find suspicious files that way.
If you have 9x then run the program inside the zip i've included (it's a 9x version of xp task manager) to use it unzip it, launch the program, click find window, then click process viewer.
