Detailed explanation-1: -1. Signature Detection-looks for recognizable patterns of particular malware within executable code. 2. Heuristics-looks for more general patterns than the strict signature detection approach, so that it can hopefully detect an entire family of similar malware.
Detailed explanation-2: -Heuristic-based detection uses an algorithm to compare the signatures of known viruses against potential threats. With heuristic-based detection, antivirus software can detect viruses that haven’t been discovered yet, as well as already existing viruses that have been disguised or modified and released as new viruses.
Detailed explanation-3: -Heuristic analysis is a method of detecting viruses by examining code for suspicious properties. It was designed to spot unknown new viruses and modified versions of existing threats.
