Generic detection refers to the detection and removal of multiple threats using a single virus definition. The starting-point for generic detection is that successful threats are often copied by others, or further refined by the original author(s). The result is a spate of viruses, worms or Trojans, each one distinct but belonging to the same family. In many cases, the number of variants can run into tens, or even hundreds.
Generic detection involves creating a virus definition that is able to identify all threats belonging to the same family. So when ‘NewVirus’ appears, the definition created to detect it will also successfully identify ‘NewVius.b’, ‘NewVirus.c’, ‘NewVirus.d’, etc. if and when they’re created. Such techniques extend also to detection of exploit code that may be used by a virus or worm. While generic detection is not guaranteed to find all variants in the family, it has been used with considerable success by a number of anti-virus vendors.
