Lab results try to show which is the best Windows 8.1 antivirus

During November and December 2013 we continuously evaluated 25 home user security products using their default settings. We always used the most current publicly-available version of all products for the testing. They were allowed to update themselves at any time and query their in-the-cloud services. We focused on realistic test scenarios and challenged the products against real-world threats. Products had to demonstrate their capabilities using all components and protection layers.

AV-Test has generated scores for protection, performance and usability, with each score ranging from 0 to 6 and making a total score. Protection means how well the antiviruses blocked malware, a score of 6 means 100 percent of malware or almost 100 percent got blocked. Performance measures the product’s impact on the system speed. So, here are some charts (pictures via Zdnet) that show which was the best antivirus solution in their opinion.
