A note for one of the stickys above im sure you can download spyware doctor with the google pack for free, its not the full version but it detected lots of malware etc on the wifes laptop from where she had been surfing tv links and all the other programe donload sites.
Regarding anti virus unless you have the most powerful pc in the world or just like wasting time on your pc do not use norton, me personnaly i use avg free and does the job for me (ps i get free norton on our laptops with our bt broadband service so its not the cost).
