Virus Bulletin and the VBSpam evaluation program

Based in the UK, Virus Bulletin started in 1989 as a magazine dedicated to the detection and prevention of malware. The magazine quickly became an industry reference. For many years now, Virus Bulletin has also been providing independent tests and ratings for antivirus products. In 2009, the company launched VBSpam, a program that evaluates the performance of Anti-Spam solutions. This program enjoys considerable brand awareness and some of the leading companies in the Anti-Spam business take part in it. Participating providers who take part in the program pay to receive a live stream of email every two months. Virus Bulletin then determines each provider's catch-rate and false-positive rate and publishes results reports that are available free of charge.
