My new computing system!

bearing in mind I have been using avg for a number of years on at least three incarnations of window$, I have read on several occasions that one reason for avg's high detection rate is the number of false positives.
I don't mind too much on my system as long as it keeps me clean and doesn't hinder me. which it does and doesn't respectively, and i've created plenty of opportunities for contamination.
many prebuilt pc's are sold with nav preinstalled, with free updates for a limited period of time. experience with other people's setups has shown this to be frequently obtrusive and i usually reccomend substitution with avg.
