I.E. "ghost" files

Forgive me if this is old news, but, when I run the cleaner (great program!) it always find KBs and files in I.E.. I never use I.E., only Firefox. Does anyone know why this is?? Seems odd. Thanks. Jesse

I.e. is an integrated part of many programs (including bits of windows itself) that is where these kbs usually come from (if it were MB or GB every time like a poster earlier today had, I say it'd likely be something else though)

Thanks! Jesse
