For example, let’s say there are two viruses. Virus A and Virus B. Both of these viruses are in the same family. Hence, both of them are using the same signature code inside their code. Therefore the anti-virus can detect both of them. You can say that this type of detection is more accurate than the heuristic analysis detection.

Heuristics analysis uses something like behavior monitoring and that means it monitors the suspected file behavior and see how it reacts or how it acts. There are two ways on how it monitors the suspected file. First of all, the anti-virus will check the file instruction and if the file instruction is to delete important file system, it will marked it as a threat.
