They can start off by making their own products compatible with each other. Symantec is a bit of a memory hog, but I could live with that. The problem is when their firewall and A/V suites incessantly fight with one another, and refuse to be removed, you end up having a major problem on your hands. The free offerings from Grisoft and ZoneAlarm are a better fit for about 90% of users.

I have Norton Internet Security, it comes with firewall and Antivirus, works pretty well... I test it at grc.com(shields up) at it says true stealth

If you get it configured right to begin with, you are usually in the clear. I work with VPN's and I have basically forbade anyone whose VPN I configure from running any Symantec product. My main contention is that for the $50/yr subscription price, you are throwing your money away first of all, and buying a potential maddening problem. A free firewall from ZoneAlarm, and the AVGfree Suite from Grisoft are just as effective, don't use anywhere near the resources, and are virtually trouble free.
