Ok, I've had tons of computer problems in my lifetime, and most could be resolved by just searching forums. I seem, however, to be stuck.
Currently, I'm using my sisters' old laptop. When I got it, it was full of "malicious software", so I ended up getting rid of her old antivirus and installing NOD32. Everything was fine and dandy, untill a few days ago when I realised that when I search in Yahoo and Google, and click on the link to the websites that come up, I'm brought one of a few "one stop search" sites. I've tried searchin with altaista, and that one seems to be working.
An example:
I search "Dog Wikipedia". The first page to show up is:

Dog - Wikipedia, the free encyclopedia
From Wikipedia, the free encyclopedia. This article is about the domestic dog. For other uses, see Dog (disambiguation). Subspecies: C. l. familiaris. Canis lupus familiaris. The dog is a mammal in the order Carnivora. ... Your continued donations keep Wikipedia running! Dog. From Wikipedia, the free encyclopedia ...
en.wikipedia.org/wiki/Dog - 112k - Cached - More pages from this site - Save


I click on the link, and it brings me to:
One Step Search :: dog wikipedia
I've tried Adaware, Spybot, neither worked.
