What's the best antivirus software, and how can you tell? When we review security software at Download.com, we do hands-on testing, looking at everything from user-friendliness to virus eradication, but we also look at test results from independent institutes like AV-Test and AV-Comparatives. These labs do not produce their own antivirus software and perform rigorous, objective tests on security suites from all major manufacturers. Here are the consumer security apps that recently won the labs' seal of approval:

As always, remember that malware constantly mutates, so it's important not only to download highly rated software but also to update it regularly. Keep all your software -- not just the security apps -- up-to-date for the best protection.
