Best lightweight antivirus?

Windows & ultimate media server going to be running in my living room. Also will be browsing web & downloading some media. Need a very lightweight antivirus -- its a low power consumption cpu, so performance is key. Thanks!

ideas?

Well in my opinion cloud computing AV is the best solution and HitManPro is the answer.

You can use ESET Nod32 Antivirus. Its one of the best available in Industry with low cpu utilization.

I changed from AVG to Avast and is definitely lightweight.

Don't think only about lightweight because antivirus must be effective. If it is only lightweight without finding viruses there is no sense to install it. In my opinion the best free is Avast and it is not so heavy.

I'd suggest:

Free:  Avira (http://www.avira.com/en/avira-free-antivirus)
Paid for: Eset (http://www.eset.com/)

Microsoft Security Essentials - lightest one I've found and effective for total coverage.
I tested it extensively earlier this year and have loaded it on about 150 (HOME) systems - not for business or Enterprise use.

Llke younghv ,I have been installed Microsoft security essentials , it doesnt kill the system and have had no issues with viruss withit.

Doesnt get the greatest reviews as can be slow to scan.

But free and a small footprint, ran it on a pentium 4 with 1Gb ram and running Windows 7 without issue.

I'm running Avira on:
AMD Athlon 1GHz, 786MB ram, XP Pro SP2
P4 2.2GHz, 786MB ram W2K SP4R1

and MS Security Essentials on:
AMD Athlon64 3200+, 1.5GB ram W7 Ultimate

and hardly notice them running (though I do disable BootScan and Auto Update on my AVs to let the computers boot faster).
