the CoolWebSearch will sort out the exact problem that you seem to be having.
When you're using the Hijack This program you just need to put a 'tick box' on any of the items that mention 'coolwebsearch' or any other dodgy search pages that have been appearing lately - and then click on "Fix Checked"
It will look something like this... and give the PC a reboot then when you finished and your internet access should be much improved.
