Not sure if you need anything else, but I rec'd the 30-day McAffee demo with the system and it's going to run out soon. So I'm wondering what Security (preferably free) would be best.

Thanks in advance, Chris

The PC tools firewall is compatible with vista. I had put it on my sisters dell for her and was working good. But then she couldn't seem to get on the internet but I think the firewall was just blocking it, and she is kinda computer illiterate so she didn't know for sure what to do. But I would give that a go and see if you like it.

I have Avast Pro on my laptop, its not free but they do have a free home edition
(avast.com) excellent antivirus.
All I have on myt.com laptop is Avast Antvirus - Windows Firewall and Defender been usng it for 1.iyears now and have never been infected (touch wood)

erm, vista compatible swcurity software............
try
AV: Avast Home Edition (or Pro if you want to pay)
FW: Comodo Firewall Beta (it works, just a few bugs, not many though)
Spyware/Malware: Either Spybot: S&D or Windows Defender

As long as you have some kind of protection, any kind is better than none.

Im running AVG antivirus , Webroot spyware and I just found this Free anti virus here that looks safe . I dont know if it is as good as AVG or not . And it says that it is xp / vista comaptable too. http://www.pctools.com/free-antivirus
