keep your operating system and applications up to date. Secunia PSI (free for private use) is one of the best tools ever for this. Running as a user with restricted rights is the other good practice.
I prefer Avast Pro version 5 as probably one of the best anti-virus programs ever. AV comparatives gave it third place because it doesn't always catch viruses on upon scanning. What they don't tell you, is that Avast almost always catches the virus using one of the all time best heuristic engines ever devised, to catch the virus BEFORE it installs, it may reside on the hard drive,but only in dormant mode. CCleaner can take care of those.
Awill seems to prefer concentrating on that feature alone; and I find I like it that way. As long as the undefined virus does nothing, Avast may ignore it for a while, then when a malware scanner queues up, or the virus makes a move - BAM!! - Avast nails it! Avast does not need a verified signature to nail the miscreant to the wall. It is then quarantined and sent off to Awill's labs to determine if it is dangerous or not. Avast is the ONLY anti-virus that I've learned does not need manual scanning. I never use the scanning feature on my honey pot in the lab; I only do a scan once every six months or so, just to be sure the performance is still up to Avast standards.
Avast works absolutely famously with all the best malware real time protectors like MBAM, SpywareBlaster, AdAware, and Super-Antispywayre. In my experience, I have NEVER had a false positive with Avast.
Avast version 5 now supports GMER rootkit technology, and sports a script blocker that is more sophisticated than NoScript from Mozilla!!! GMER is probably the most trusted rootkit technology out there. It also picked up anti-malware capability last year also.
Now FireFox only has one advantage over IE 8 and that is The spell checker.
I finally switched to Avast now that the new version is out, as I have had such good success on the free version for my clients for many years now.
The best defense is a blended/in-depth defense, that I am only touching on here in this post.
I do not work for any person or company, I just hate malware to pieces!
