extremely slow browsing

I've got broadband (10mbit), a hub & use xp. Everything was fine until about a week ago, when webbrowsing became extremely slow, slower than using a 14.4 modem, some pages take more than 5 minutes to load. The strange part is that I play alot of World of Warcraft where I don't have any problems (no lag), dc++ works fast too (same download speed as before) I also did a connection speed test which showed good receiving speed, but timed out on the sending part. I use f-secure & spybot search n destroy but they haven't found anything. Does anyone recognize this problem or know what to do?
greetings Karl

 

I'm assuming you already tried clearing out your cache in internet options. If so here is something that I saw fixed this on someone's else pc with the same exact issue. Go command prompt and type ipconfig /flushdns
