Antivirus suggestion

Is there a good antivirus software besides norton and macafee?(both of those two aren't good)

I'm having a devil of a time with norton and I'm just sick of it spamming me and reconfiging itself all the time. I tried macafee along time ago and it instantly had to go. Panda looks interesting, But I want your oppinion.

Thanks.

It will work if one doesn't fail at configuring it. Problem is most users fail.
