hmmm all the antivirus i have use b4...norton, mcafee, pc-cillin, AVG and Antivir
The one that eat allot resource is Norton, mcafee and pc-cillin scanning not that infective....

AVG and Antivir for those who know how to care there pc then should not be problem of using them...Because i heard that some people say not that good...anyway it not a resource eater and depend on u....

For better protection try out Bitdefender 10 and Kaspersky Antivirus 6.0 this both is worth buying original...Currently i using Kaspersky Antivirus 6.0 only cost about RM 55 it's expire date until next year...depend when u buy and u use it....always up to date...

Kaspersky version 8 looks cool.... hope it wont eat the system resource.. Any1 testing it? Izzit way better then version 7....

Bitdefender Free Antivirus working great on my sister laptop Windows 7 64bit Ultimate the website blocking working good i tested already there is a review on it. http://www.youtube.com/watch?v=hf-baaHAUPw...xg-_5Sg&index=1

Yes Antivirus really protect us depend which product u use... But what i think best for me is Bitdefender and Kaspersky. For example if didnt use any antivirus ur computer infected by viruses, worms or trojan it's gonna be big trouble such has ur information will leak to other people pc or virus keep on spreading on ur hard disk and if u insert ur pendrive to ur pc which got virus then it's spread to ur pendrive then u go to ur friend pc which dont have antivirus u plug in ur pendrive it's will auto spread to ur friend hard disk has well.

Your friend might be a gamer that doesnt want the pc to go lag cause by antivirus?
Or maybe he know what he is clicking?
Maybe your friend has allot of viruses on his pc then he wanna spread the virus to u ask u not to use any antivirus?
Just kidding hope ur friend is not bad.
