u can also use intellegent updates instead of live update...dese are installation files which u manually install...but they cant be automatically downlaoded on ur oc u gotta go to da website symantec.com and do it urself every once in a while...
also, digit keeps on giving the latest definition updates so u dont need 2 back em up cuz u'll waste space (yes, i kno dey r only 3-4mb but still...)
