What are the best softwares out there?
Theres..

Norton
McAfee
AVG
Avast
Trend Micro
And I just heard about Eset nod32
And more

I use McAfee atm since it came free with my ISP.

What are the top free/commerical softwares?

I've used AVG Free and I'm currently using Avast! and they've served me well being free and all. I'd prefer to use them than pay for software like Norton or McAfee especially.

None.

I use AVG after getting rid of NORTON and then McAfee (which both took up too much in terms of resources and my time).

Avast is the best! Word to your motha.

Linux?

MyBrain

Yous should try it!

AVG with Spybot for adware

Right now i use BitDefender. Eset is good , Avast is the worst anti virus i ever had.

Norton, because my father buys it every year, and you can use it for 3 PCs, so i'm currently using it. I would say that, despite what someone says, it's a very good antivirus, and it's also lighter now...about the free Anti-virus i can say that AVG is the best...
