Selecting antivirus is a very important step to protect your computer and here you need to look at the following:
- How regularly you update the software.
- How regularly and extensively the manufacturer updates the virus definitions.
- How good the software’s heuristic scanning engine is for detecting virus-like activity.

But to select a good AV you need to consider special security labs that are testing antiviruses against latest malwares and checking their regular update. Virus Bulletin test results, Known as the VB100.
The VB100 looks at average reactive scores plotted against average proactive scores for each product. Products which manage to detect 100% of the viruses in the wild, without false alarming, are given the VB100 award. Here is a test for Windows Vista x64:

You can have all results on the official website.
The last and not least independent Antivirus testing lab is AV Comparative an organization that provide independent Anti-Virus software tests free to the public.
