No offense, but if you are careful about these things then you really wouldn't be using IE to surf IMHO - too insecure - just surfing to the "wrong" site can cause you to be infected.
I tried IE6 and IE7 and I didn't get anything like that here - it must be a local infection pal - go to:
www.trendmicro.com
and do a free full online scan - let us know what it finds! Btw - keep running the online scan until you are completely clean.
