I am running Windows OneCare Live (beta 1.5) - which is free for 180 days, and then is priced at $49.95 for a 3 computer license (although you can find it on sale for around $29.99).
I like it because it has competent firewall, anti-virus, and anti-spyware all in one, which combined with the anti-phishing filter in IE7 and the Outlook spam filters - works quite well.
The biggest plus is that I now have only 31 processes running with XP loaded, which is down from 37 processes when I was running Norton Internet Security 2006.
Although Microsoft is new to the security market, they have a good package if you are an average home user who wants some measure of security. Their network of security databases is quite extensive, and is always updating.
IMO - the OneCare Live package is worth a shot for those who are fed up with bloated suites which seem to need a large amount of background processes to run in real-time.
