A simplification, if you will

At the risk of a geek freak-out , Here are the anti-virus choices that matter.

Lighter: NOD32

Heavier (notice that I said heavier, not heavy): KAV

 

All of those with the Advanced + rating at AV-Comparatives would have to be in there.

 

Lighter: NOD32

Heavier: BitDefender(maybe light??), Norton, McAfee, Kaspersky

Lightest: F-Prot

 

BitDefender isn't heavy. Memory usage maybe seems to be high,but it works very light on the system. Fact that i'm running it in a VirtualPC with 128MB and installed WIndowsXP SP1 is enough i guess,because it works very fast even for VPC. I remember how long Norton or Trend Micro took to start all it's stuff not to mention time to perfrom any other task later...
