OS = WinXP with ADSL internet connection.
I have Norton Anti-Virus with an on-line up-date subscription in place.
My question - Is it necessary to get a Norton Personal Firewall as well - or is the Norton Anti-Virus good enough to protect my pc?
From reading previous EE queries it seems pretty clear to me that I should not mix brands of security system for fear on incompatibility between them. So I wish to keep this question confined to Norton Personal Firewall.
