PC Tools Firewall Plus - Cancelled as of December 4th, 2013

This year, in March, my computer had…a memory implosion (I never uninstalled steam games I didn’t play), and the hardware specialist I was contacted with installed avast! Free antivirus, Norton 360, and PC Tools Firewall Plus. Recently, I googled it. Apparently its being cancelled. What do I do?

What do you mean with “memory implosion” ?
Never install/use two av’s at the same time. (avast + Norton 360)
Why a software firewall and not a hardware one?
What is cancelled?
What exact version of avast?
What os/service pack?

And most of all… What is the problem?

the hardware specialist I was contacted with installed avast! Free antivirus, Norton 360,
Not much of a specialist if he installed two resident AV programs on your computer. That one move is enough to kill almost any computer. [b]Decide which AV you want to run and totally remove the other. [/b]

+1 and remove the PC Tools Firewall.
