I am strongly against all in one products. I would recommend something along the lines of kaspersky or nod as they are industry leading antiviruses. I would then recommend using comodo firewall, if you do not feel secure enough using the built in windows one. Throw in adaware or superantispyware and you should be set. Personally, I feel Symantec has come a long way and internet security 2009 isn't horrible, but it isn't the best possible decision.
