He Hong · Information Security and Communications Privacy · 2007
The defination of viruses is the basis for the research of anti-virus technologies techniques,and the security experts till now have not had an exact definition of the distinctions between the virus and the ordinary programme.According to the most common destructive file-type viruses,this paper,take the user's desire as the judgement criterion,gives its formalized definition,upon which an algorithm for exactly recognizing the virus is formulated.The analysis on the case of actual malicious programme indicates that most of viruses are within the limits of the new definition.
