The VB100 certification programme has been in operation since 1998, the certification being awarded to products that meet the basic standards required to be recognised as legitimate and properly functioning anti-malware solutions.

The VB100 certification itself is designed to provide a stamp of quality and competence, and to demonstrate that a product is capable of meeting the test expectations in a consistent manner.
