VB plans a review of the test procedures for the VB100 comparative testing and certification program, after some issues arising from the recent Linux comparative have brought to light a lack of clarity in the publicly-available procedures document.
The methodology of the tests insists that, to qualify for a VB100 award, a product must not raise any false positives while scanning our set of known-clean files. However, files flagged as 'suspicious' are allowed and do not count as false positives. In the recent Linux comparative, ESET's Nod32 product flagged one clean file as 'probably unknown TSR.COM.EXE virus', and was thus adjudged ineligible for the award. This decision was queried by ESET on the basis that such a detection may be considered a suspicious flag rather than a full false positive.
