I have used AVG free antvirus for several years and really like it. I have also just completed my 30 day free trial of the antispyware program (formally ewido) and was impressed with that too. The AVG security suite is available on a free 30 day trial. Why not try it first before decididing whether to part with your money. I do think the suite is good value though at £40 odd for two years support and updates.
