illegal operation

all games that i install say

"internet explorer has performed and illegal operation"

specially nba live games...

is this a prob with my card or explorer?

tnx

likely it's explorer. i just finished fixing my dad's laptop and desktop, and this was one of the issue. I can't exactly tell what the problem is, but i found 29 viruses and trojans. Clean up your computer, and use Hijackthis or something.
