Hi Jaxxy,
Have you got a virus checker installed on your 'puter?... if not, get one!. Make sure you keep it up to date (most of them have a facility where you automatically have it download the latest 'signature file' to keep your system protected).
Secondly, I would download a program called 'adaware', this will search and remove any traces of 'spyware' from your PC. Adaware can be downloaded from :

or a direct link....

I've used Adaware successfully many times before, and I'd recommend it for removing spyware...
PM me for more info...
