My favorite is Panda Titanium Antivirus: http://www.pandasoftware.com/
If you want, you can also get a free online scan:

I like free, but I hessitate to take Comcast up on the free McAfee offer
only because of the problems I had with McAfee in the past. I once found
myself in a loop while trying to update the software (not just adding new
definitions). After getting out of the loop I found the software broken,
unable to reinitiate the update, and unable to automatically uninstall. By
the time I got things back to normal, I wasn't interested in reinstalling
McAfee.
I don't like Norton because it does too many things in the background, and
didn't respect my choices to turn-off some of these unnecessary background
processes. Kind of ironic, since one of the things it was suposed to protect
me from was programs running unauthorized background operations. It also was
a bear to uninstall.
I spent a couple years using the online, free virus scans from Panda before
I spent the money to install the program on my machine. It installed easily.
I can turn things on and off reliably. It hasn't crashed anything. And I've
updated the engine a couple of times with no more difficulty than updating
the definitions file. I don't know how easy it is to unistall it as I
haven't had a reason to uninstall it yet.
Admittedly my bad experiences with McAfee and Norton are based on old
versions of the software, long obsolete. But when I was using them, it
seemed that anytime a bug was fixed, they just had to add some more bells
and whistles that were even more buggy. And it seemed that every time
Microsoft made a significant update, McAfee and Norton didn't get along with
it. I haven't had those problems with Panda probably because it isn't as
invasive when it installs. It doesn't try to become part of the OS. It knows
it's just a program that needs to run on the OS.
BTW: I don't get paid to push Panda. They pay me nothing. You can buy it,
and I get nothing.
But... If you want to line my pockets, you can use this link to buy it:
http://www.amazon.com/exec/obidos/ASIN/B0006LCHX6/ref=nosim/holzemville-20
I also get paid if you buy Norton through this link:
http://www.amazon.com/exec/obidos/ASIN/B0002UCSKI/ref=nosim/holzemville-20
Or PC-cillin:
http://www.amazon.com/exec/obidos/ASIN/B00068IBZW/ref=nosim/holzemville-20
I could give you a link for McAfee, but since Comcast gives it away free, I
won't bother. But my point is, I don't get paid to push one over the other.
My opinions are based on what I think is best, and is not a paid
endorsement.
