Last week I received a Dell Inspiron 3500 laptop. Specs are: 266mhz PII, 64mb 66mhz ram, 4.2gb hdd. I've installed windows 2000 pro. The network is provided by a netgear USB adapter, which plugs into my linksys router. As it stands, I have about 26mb of free ram (lots of services shut down). Plenty for surfing the internet (firefox) and DOS gaming. Spyware is no problem because I have adaware and spybot.

What I do wonder is about a good small footprint anti-virus program. I've really only used norton and mcaffe (in the past) on my desktops, so small footprint and low system overhead is unknown to me. I've done some searching and came up with 3 contenders...

1. ETrust EZ antivirus - website says 100k system footprint - $19.95
2. F-Prot - "without draining your system’s resources" from their website - $29.00
3. NOD32 - won awards for scanning in the past (website) - $39.00

So, without breaking out into a huge "which is better" war... I would like to know your experiences with these (or other) small footprint anti-virus programs.

Also, please don't say "install Linux" because I'm already in the process of getting a distro ready so it will be dual-boot. And a firewall program won't be necessary because of my (relatively) secure home network and fully-patched OS.

Any ideas?
