Many simply disable the firewall, antispam, and use only the AV program.
You can download Zone Alarm (free edition).
It's an excellent firewall, and all you really need.
The other programs seem to create more problems, rather than solving them.
Also, changing to Firefox (free download)
for your primary browser offers many security advantages and it has it's own pop up blocker.
Everyone seems to have their own formula for security, but I've found that this works well for me.
Firefox browser, Norton AV, Zone Alarm Free, Adaware, Spybot Search & Destroy, Microsoft Antispyware Beta.
All except Norton are free and do a good job of keeping the pests away.
Best of Luck
Ihave a pentium 4 2.8 ghz running xp home and think I am having terrible problems with conflicts between windows,norton security suite and firefox. I am ready to remove norton and try Steganos. Has anyone used it and were they satisfied with it?
