Security obfuscates a virus’s unsecured personal fingerprint to the level that it can’t be matched having a known computer virus. Other strategies include adjusting the signature, hiding portions of it or perhaps obfuscating it entirely.

Heuristic-based diagnosis is another way of detecting dangers. This type of recognition compares the malware’s code to a list of common attributes that are characteristic of malware.

Behavior-based detection uses a equivalent technique yet examines the behaviour of a data file or program instead of their signature.
