which antivirus/internet security do you'll use & are u satisfied with it?i used to initially use norton internet security but since it used to eat too much RAM, so now i've shifted to eset smart security 3.0...is there a better AV/internet security software?my main requirement is that as soon as i insert a flash drive, it should remove the viruses as it used to happen in norton but in case of eset SS 3.0, it sometimes does that but otherwise the removal happens only when i manually scan or open some sub-folders
