I've read the Reviews, but am not able to decide which one to use. What I want in the AV: 1) Obviuosly a good protection from viruses, trojans, spyware etc 2) Least memory intensive 3) Should give option to disable it from a normal User account also (in XP) 4) Should give a detailed name of a malware when found (I hate the name Avast shows - just like Trojano/123) 5) Should give option to exclude some folders from scanning 6) Updates 7) Should have a onAcces scanner 8) Don't need email scanner 9) May or maynot be freeware I've tried 1) Mcafee 9 (only for a few minutes) - Very memory intensive 2) Panda Personal - Slowed down startup, didnt look satisfactory 3) Avast free - Nice but not good in detecting and not satisfactory virus names 4) BitDefender - I liked very much, not much memory intensive. Only thing for which i removed it yday is it freezes Opera when its loading a page and i cant do with opera freezing every now and then 5) AntiVir - Temporarily installed till i get satisfactory response from here, but i find it very less memory intensive. Extremely happy with it, but i dont know how good its detection is. I tried testing it with EICAR, it detected .com while downloading, but didnt detect .zip and .txt.
