i need a good anti-virus, or any other syware remover that not eating the memory too much.

malwarebyte?

full package antivirus + firewall + antispy + optimizing tools + low resource = Norton 360 v5

well, as i said, i want an antivirus for gaming, low memory usage

Try this http://www.pctools.com/free-antivirus/

make your own decision..

lowest is the best? so avast is the lightest?

you can give Microsoft Security Essentials a try also. not bad, doesnt bother you at all.

Avast ? you can say so. got positive response from users too
for spyware remover, i suggest Malwarebytes. only affect pc performance while scannning...

what about AVG??

Free or Paid?

If you want real-time protection, sure will reduce your memory. Therefore, you need to choose those AV/Protection that comes with Game Mode such as BitDefender or Comodo Firewall because I don't suggest you to disable the real time protection totally unless you make yourself disconnected from the internet.

i'm using Comodo Internet Security,it works fine.!

Probably not kaspersky, because its heavy.

Panda Cloud Antivirus(cloud-based freeware). Lightweight and no false positives reported so far.

hehe, suggest u to try Trend Micro, which is less memory needed one...

avira is less also what.. been using it and it did not affect my gameplay

Avast looks great
