The Win32 platform executable worms have been the most widely distributed malware for a long time. The presence of heuristic detection may decrease the risk of new worms. Heuristic detection is possible if a new worm is more or less a re-development of an existing one, using at least the same method of replication.
For heuristic detection, we need to know the file structure and viral features that the worm uses.
The worms are classified by compiler type (lowlevel, MS C, Borland C, Delphi, Visual Basic) and by their method of replication (SMTP, MAPI, OLE, network shares, IRC, ICQ , secutity holes etc. ). For each type, the methods of replication and the possibility of heuristic detection are analysed.
