polymorphic virus

A virus that changes its binary code each time it infects a new file. Without an identifiable pattern to match, it is extremely difficult to discover under normal methods. Also called a "stealth virus," one way to detect it is by its actions (see behavior blocking). See virus.

Glossary of virus-related terms by The Newsletter on Newsletters In order to obtain the ICSA On-Demand/On-Access Anti-Virus Product Certification on Windows 2000 systems, AntiVirus Expert needed to detect 100% of the viruses currently known to exist "in-the-wild", as well as, detect 100% of the ICSA Lab's test suites, which included a polymorphic virus test set and those viruses known to be common infectors and have yet to be named to the WildList.
