Comparison Date: 5-July-2011.
¹ The Meta-Score is calculated by combining the normalised scores of the two leading, independent anti-virus testing organisations, AV-Test.org and AV-Comparatives.org. The result is given as a percentage. Only products which have been tested by both organisations in their most recent test run are included here. In the case of a tie, the products are ordered based on Value.
² The Price is taken from the global/US website of the Anti-Virus company, current price as at 5-July-2011.
³ The Value is determined by dividing the Meta-Score by the Price, and then normalising the result on a scale of 1 to 5. Products which are free are automatically given a 5 star value rating.
