IE acting up, hijackthis log inside

Hello,

A friend having problems with IE, lots and lots of porn adds(the usual stuff), I cant seem to find a way to get rid of them . Have ran spybot and adaware.
Here's the log:

Logfile of Trend Micro HijackThis v2.0.2
Scan saved at 18:14:20, on 16.6.2005
Platform: Windows XP SP2 (WinNT 5.01.2600)
MSIE: Internet Explorer v7.00 (7.00.6000.16574)
Boot mode: Normal



After taking the log, I tried removing IE7, it went OK. But now as soon as I open IE(6) it shuts down, prompts "save file ______"(=name of the page I'm trying to access).

Thanks
