My uncle's computer is really acting bad. He uses windows xp pro and i think its a pretty new computer though its running very slow indeed. When its turned on something comes up saying a website is trying to connect to the internet- this site changes every time though some of them are obviously bad using 1337 in their names et all. Actually connecting to the internet (BT broadband) is iffy, I only got it working once after many trys and then a midoom style the computer is shutting down in...counter came up.
So what is this? Does midoom have a dialler? How do I go about getting rid of it? He doesn't have a firewall btw.
