Consumer Reports recently came under heavy fire from some in the anti-virus industry for creating some 5,500 new virus variants to see how well a dozen leading products fared in detecting the new nasties. More than 100 security experts and executives from companies like Microsoft and HP as well as anti-virus vendors F-Secure, Kaspersky, McAfee, Sophos, Symantec and Trend Micro signed their names to a declaration denouncing Consumer Reports' methods, stating that it is "not necessary and ... not useful to write computer viruses to learn how to protect against them."
