Okay..I don't download updates. Don't ask why. But after using HouseCall(the online Virus Scanner), most of the results are "critical updates" which I have to download. Am I still at risk even if I have the whole security package - Antivirus(AVG and Avast), Antispyware(Spybot: S&D, Ad-aware, Spyware Blaster), Antirootkit(AVG) and Firewall (PC Tools..which is about to be replaced by ZoneAlarm)? Please help! Thanks.
