There is no "best" best is subjective as no doubt this poll will demonstrate. What there is however (as shown by the testing institutes) is a number of products that consistently offer high levels of protection.
I agree with the no best as there are a lot that will do the job , I chose Kaspersky because I have been using it for years and I got a rebate of $60 on the software that cost $60 , so for me it was free with the rebate.

No Avira ? Trusport, Vipre ? And yet Mcafee is there ? I use Trustport and Vipre , with outpost pro and Spywareblaster , so far no problems . Used to use Avira , but it got a bit bloated and slowed things down a bit . So far he new AV are light , work welll with the firewall and Spywareblasrer .
