Hello everybody, Because my computer is quite old (intel E2140,4GB RAM), so i hope to run the lightweight antivirus. I searched some info on internet, found that NOD32 should be quite ok, but after i installed it, it is too slow, i tried different configuration already but the performance just improve slightly only. I already disabled web access protection, email protection, scan all files, advanced heurisric. Is that any other things i can do? Actually I am holding the original version of KAV 2010, BAV 2010, NOD32V4. None of them can run smoothly in my windows xp. My current security setup is: -Comodo Firewall+HIPS -Spyware Terminator -Process Guard -Avast AV free -ThreatFire -Sandboxie Perhaps I should abandon the above listed software just go for ESET Smart Security would be better?
