At the end of every year, AV-Comparatives releases a summary report to comment on the various anti- virus products it has tested over the year, and to review their high-scoring products too. This year, the top overall award goes to Kaspersky Anti-Virus. Anti-virus tools from Avira, Bitdefender, ESET and F-Secure were also highly rated. We last wrote about their 2010 test results here where F-Secure won the top berth.

Here is a summary of the different products tested and how they faired.

There are a number of other winners in different categories, such as the fastest scanner, the least system impact, and on-demand protective features. You can download the full the report here. Certainly, if you are looking to switch AV vendors this might be a good time to review what they have found.
