Query: DONT BUY NORTON ANTI-VIRUS PRODUCTS UNTIL

they fix the numerous problems with their NAV suite; there are plenty of folks who have suffered after downloading unworkable virus definitions and you can not get in touch with Symantic to resolve problems. They take your subscription money ($29.00 US) and then leave their customers in the dust with non-working software. BOYCOTT SYMANTIC!!
