How to Reset Security Certificates?

Well once again I made the mistake of letting one of my friends play on my computer. Needless to say anytime one of the security certificate warnings popped up he just went ahead and clicked yes I accept. Well now I get random popups I never got and my computer will just connect to internet explorer on its own.

What I need to know how to do is reset all the security certificates so that next time I go to a website it will require me to "trust" the website and its data. (ex. when you went to windows update website for the first time it asked if you wanted to trust them or always trust windows updates)

I already deleted all cookies, temp files reset security to defaults but it still hasnt deleted the certificates cause when I go to update it just jumps ahead


Background info
I am running windows XP home edition, latest internet explorer, I already ran adaware and spy bot S&D, ran my virus scanners, it for some reason came up with one thing that was just some random numbers, i got rid of that. Any help would be appreciated

I would suggest that you need to look in the Windows Hosts file?
