How is it viruses spread these days? If it's through applications being copied, installed or downloaded, you could avoid that issue by not letting the OS install any applications (or, iPad-style, only let approved applications be installed). If it's via security holes in the OS then you could make sure your OS stays up-to-date properly. Are there any other ways a virus infects a computer?
The problem I have with the "I only install from trusted sources" approach, is that you have no way of being certain that the sources security has been breached, thus allowing that installer you're placing your trust in to inject a virus as it goes. And does anybodies PC really slow down that much that they're willing to take the risk?
AVG used to slow my PC down a lot: that was the software's fault, not just because it was antivirus. That is why I now use avast as my run time AV, and I don't notice any considerable slow down.
I solved the problem with AV slowing my machine down by using MSE at home. It's pretty lightweight.
Having had to unpick a few nasties in my time, never on my kit thankfully, I prefer to have AV on all kit at home that connects to the internet. It's not as if I run any 'heavy duty' software that needs every bit of help it can have to run at a decent speed.
I'm a mere mortal so therefore it is possible my kit will pick a virus and frankly I spend far too much time fixing stuff at work to want to spend my free time doing the same.
I dont but do know a small company with 5 pc's and no antivirus. God knows what is on there pc's
I always do. I'm fairly confident that I wouldnt pick anything up but why take the risk when an AV program is free and doesnt take up too much resources.
I dont on my Macs though...I realise I should but I dont really know any if I'm honest (in the same vain as AVG)
ClamXav for my Macs, mainly to catch viruses and nasty code in documents which pass through my systems on to elsewhere. Remember that even if they don't kill your machine because you are patched / using a low risk OS* then it may kill others. I catch about 4 a month at the moment.
*discussion of the lowness of risk of the relevant OSes have been done to death, but no OS is going to be safe forever!
we dont run any AV on our virtual desktops as they are read only, the servers do have Av so any files being saved are scanned also email and internet is scanned at the boundry
ESET is now out for Macs too.

Nope, All of my computers/servers at home are Installed with ESET NOD 32 Anti-Virus.
Admittidly i have run a desktop in the past which no anti-virus on (just firewall) and i never had any virus's etc.
