I use the McAfee corporate version. I used to use Antivir, and switched to the McAfee(the corp. ed.), and I can not see any decline in the performance of my computer.
Once you grant access for all programs that need it ZONE ALARM is the way to go. She wouldn't even know it's there.
Norton sucks..
i have McAfee Corporate 8.0i and i've never noticed it hogging resources unless it is running the balls to the walls virus-scan... but the regular on-access scan is very good... it catches viruses before they are downloaded and ran...
Well, because my mama (only54) has had prior use with AVG and had no problems ive decided to get her AVG 7.5, now ive just got to scout around for a firewall.........................and yes ill have a look at Zone Alarm.
Thanx guys.
EDIT: Gone for Comodo, looked at a few reviews and it seems miles away the best (i hope so), just infront of Zone Alarm
