avast! Free .
thx,not really looking for free antivirus,used avast in the past and wasn't so happy with it.
Eset Nod 32 + malwarebytes. Been happy so far. Although they didnt stop that damn easylife browser hijacker grrrr.
AVG Internet Security 2014 + Common Sense
No problems till today
+1 for Kaspersky too, I used it in the past and it is one of the best antivirus
+1 for kaspersky and malwarebytes. That's what I use.
