computer problem

Howdy all

I am hoping that someone with a bit of knowledge about computers can assist me.

Everytime i click on internet explorer and get my homepage up, on the bottom of my screen a blue strip appears and on it are various adverts, such as "make money", Music, Casino, travel and a few others as well as a search bar. Under properties is comes up as "Searchweb2.com/ads/ads.html" Further to this, I get a message each time I try to get a web page up I get an error message that states "script error" and then mentions URL "Searchweb2.com/ads/ads.html", the very same thing that pops up on the bottom of my computer screen

I have an antivirus as well as NoAdware and Xsoftspy and none of these are picking this thing up as malicious.

I am only seconds away from shooting this damn computer, so before I take such drastic measures, can anyone shed some light as to what is going on and what I need to do to get rid of this nuisance?

TIA

Please HEEEEEEEEEELLLLLLLLLLLPPPPPPPPP MMMEEEE!
