Best Antivirus?

What's the best antivirus out there? I had Norton but it let a lot of virus and spyware enter. I tried to download the demo for Panda, but it froze my computer, so I would like to have some opinions...

thanks!

Best Antivirus?anti virus

I have been using mcafee for 6 years with no infections.

Best Antivirus?auto protect

Trend Micro PCcillin works great for me and it is not a memory hog like that Norton garbage.
If you desire to use a free antivirus, I would recommend Avira from Germany (Being that I am a beta tester for all antispyware/antivirus and other new software. This program is rated as good as Karpersky Russia or NOD32.

If you wish to pay then you may want to take a look at the antivirus that I use for the past ten years and never had one virus. Plus you can evaluate the full version for 90 days.

Here is the data on the antivirus that I have used for the past ten years. An I am required by law due to my profession to keep my PC's 100% clean. I use an antivirus from Beijing, China. You pay only a one time fee of $29.99 for life for each PC, includes 7 or 8 daily auto. updates plus all new versions for life.
