hey can anyone suggest which one is best free antivirus?? that provides best protection n does not slow down comp..??

I'm sure i speak for many when i say Microsoft Security Essentials is the way to go!

Many antivirus in free bt tri wt rsvr85 sed

bt in my opinion "AVAST IS" IS BEST me useing too

Hey bro can i use this with antivirus programm

I doubt that is acceptable to run two AV's at the same time. MSE just might disable the other Av, but you should try it out because I haven't tried it.

Why would you want to do that? MSE is pretty powerful free security software.

There is no best.

Microsoft Security Essentials

Ok bro no prob bt it only for Genuine windows only

In my opinion, if you're using an illegal copy of Windows (yes, cracked means illegal), you probably shouldn't worry too much about antivirus, since the virus is already embedded in your system files and can't be removed.

Using hacked Windows and then asking for antivirus afterwards is like BASE jumping and remembering a parachute after you hit the ground...

hey bro i m using Win 7 which i download from torrent n its fully activated(ragisterd)

Either one is a good product. I have used both and wouldn't use any other apart from these two free programs, I currently use MSE.
