I'm having a new pc built for me. So I'm looking for a good Anti-Virus. Any Ideas on a good one.

mcAfee

Space-Boat

super anti spyware
spybot search and destroy
I deleted McAfee with two years left on the subscription because those two programs did better

Avira, Microsoft security essentials. Both are the highest rated free anti virus scanners.
Unsure what MSE needs for memory, but the running process for the Avira active scanner sits between 3-15mb of RAM for me.

I use Microsoft Security Essentials as well...along with malware bytes (payed version). The malware bytes is a 20 or 25$ (can't remember) activation fee for the life of the product which means you don't have to keep shelling out dough for licenses. It really is a great combo and won't cause you any installation problems if your getting windows 7. In xp the two products don't like each other too much without adding exceptions in both programs. I agree stay away from mcafee, especially if you don't like your computer getting bogged down. If you're going to go with such high security that a major commercial product will give, get norton instead b/c it's doing really well at the moment in all areas.
