What's the best free AntiVirus solution?

[InlineFive]

I need it for some more budget-minded customers. It should preferably be thorough (duh ) and have an Automatic Update feature, somewhat like Norton's LiveUpdate. Since I have only used Norton I dont really know what's out there.

Thanks!

EDIT: The Automatic Update should be free also.

AVG and avast are the best free ones I know of.
