Which Antivirus do you Use?

Nod32 Ftw!

Norton 360.

Kaspersky internet security 7!

Symantec Endpoint Protection 11.0

Nod32 2.7

NOD32...and ussually mcafee

And where is Avira?
Tested the most antivirus programs, and I feel Avira AntiVir works best on good security for an active sharer.
And it's free :)
Or I will recommend Kaspersky.
