IMO, I think common sense, basic hygiene practices, a minimal education and a decent firewall goes a longer way, being much better than an AV could.
For example the most common way people get infected is by installing software from unreliable sources and by not keeping their computer up to date. I'm pretty sure that learning to regularly update your OS and browser, learning to search, recognize and use the official sources for software, to stop doing software piracy for that matter, learning to not click on .exe files received in emails and to be suspicious of all attachments, learning to uninstall everything that infects your browser with useless plugins, I'm pretty sure such simple knowledge would cut 99.9% of all incidents.
Most software vulnerabilities in the wild are not novel, "zero day" exploits are not that common. This is why even though I hate Microsoft's recent update policies, on the other hand I understand their newfound aggressiveness in pushing those updates, as it is really frustrating that users ignore update warnings. I also appreciate Chrome's fast updates, which encouraged Firefox to do the same.
