hmm what did i say ....

if it doesnt happen now and nothing weird happens .. just wait until it shows itself again (if ever) .. if it does ... write down the info the antivirus program gives you)

you can then have a look at :

have a look at the 'downloaded program files'
check if there is anything you dont need in there (in case you remove something you do need, it will install itself again after asking you when you need it)

on windows 98 you can find it at C:\WINDOWS\Downloaded Program Files
and probably something similar on windows xp

on windows 98 you can also get there by right clicking on the icon of internet explorer on your desktop, then go to the 'settings' of your 'temporary internet files' and then have a look at the 'objects'
