Grrr!

[prepare4trouble]

I've got some kind of spyware thing on my computer that is changing my homepage to this advert with millions of popups, and it goes to it whenever I log into my e-mail too. I've got anti-spyware programs, antivirus programs and a firewall, but I can't seem to get rid. It's very annoying. I want to check my e-mail!

I went to check it at 1 this morning, meaning to do that then go to bed. I've been messing about with it ever since!

Is there anyone out there who had any ideas? Because I'm completely lost!
