Now, modern antivirus programs use a more advanced method of discovering viruses – called heuristic detection or analysis : which can recognize a wide range of anti-virus families simply by combining related ones into one generic signature. They can then simply watch what programs do and flag virtually any that are doing something they shouldn’t, along with monitor Computer registry changes to determine potential malware installations.
