Yeh I have just downloaded Spybot, and it found and deleted all sorts of stuff, its a feckin liberty that people like Yahoo allowed to do this.
I think it was deleting stuff from the registry with adaware was what porked my machine originaly though .
Strange thing about Spybot, after it had done its thing the internet pages like Pprune were very strange, it had altered my graphic setting to 256 colours for some reason, ok for me I can find and sort probs like that ,but like I said in a previous post your home page disapearing and settings being altered must be a nightmare for people new to computing.
