Technical Support availableTo solve this problem, some antivirus programs use a “heuristic” algorithm. Viruses have behaviors in common with each other, such as working without changing the recorded “last modified” date, or avoiding changing the size of the file. The antivirus program will recognize this behavior and find the virus by tracing back to the source. Other antivirus systems use a “baiting” system, where several files are made to look and coded to be like regular files, but are in fact closely watched by the antivirus software.
