In a Windows environment, Microsoft Securities Essentials is very good.
In a Business environment, in my own client experience, free A/V software is vastly more expensive than top line paid AntiVirus. ... Thinkpads_User

I have always found AVG to be quite good though you do have to upgarde it manually when the version changes.

Avast! Antivirus.  Can be downloaded from Download.com.  One of the few to offer Boot-time scanning capabilities.  I like that you can customize the install and only install the scanners that you need.  For example if you don't IM or P2P, you can opt to not install them.  Free version simply requires registration, and I have never gotten any spam from them.

Instead of giving you the "my type" kind of suggestion, take a look at the links
http://www.antiviruscomparison.org/
http://anti-virus-software-review.toptenreviews.com/v2/

Or search for comparision charts in the topic of virus removal accuracy etc.

Well, I'll give you "my type" anyway... :)  I use NOD32 Smart Security and I cannot complain.

I agree with thinkpads_user - either use Microsoft Security Essentials or buy something.  In a business, the TIME you spend going to each machine will be very expensive compared to going with a business class product that allows you to centrally deploy and manage.

"Panda Cloud Antivirus is the best free antivirus software available... the next evolution of anti-malware technology".

PC Magazine is a joke in my opinion.  Most "independent" reviews I instantly discredit based on their opinion of Symantec/Norton. Anyone willing to classify Symantec or Norton as better than "fair" has an opinion I'm not willing to consider good enough to listen to.

A comparison test of the free of charge AV products Avast, AVG, Avira, Comodo, Microsoft, Panda, PC Tools and Rising was published by c't and performed in close cooperation with AV-Test. The results can be found in the printed c't issue 12/2010 on pages 90 to 99.

tells that Panda Cloud Antivirus has the best detection rate! (we are talking about free antivirus products) We also use Panda cloude free by ourself and can proof its realy good! The only thing, it doesn't have is Behavioral analysis. Panda Cloud Antivirus Pro is having this.

We are useing Panda Cloud with ThreatFire (for Behavioral analysis)

The best solution is using multiple vendor antivirus engine.
There is some antivirus that have multi engine.
I prefer using microsoft forefront for email gateway, multicore antivirus, or trustport.
it's using many of virus engine from multi vendor. (Kaspersky, norman, etc.)

Virus came from many of countries, so i think you must use multi virus pattern.
But you must have extra memory to load that multiple engine.

For comparison :

Off course most free AV packages are only for use on private computers, there licesing agreement precludes there use in commercial enterprises.
