Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
One disadvantage of virus signature is that it will only detect those viruses for which signature exists.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -In signature-based detection, security systems write signatures for patterns found in files containing malicious software so anti-malware programs can detect them easily. In contrast, heuristic-based scanning uses rules or algorithms to search for commands that may indicate malicious activity.

Detailed explanation-2: -In computer security, a signature is a specific pattern that allows cybersecurity technologies to recognize malicious threats, such as a byte sequence in network traffic or known malicious instruction sequences used by families of malware.

Detailed explanation-3: -Polymorphic Virus – These type of viruses are difficult to identify with a traditional anti-virus program. This is because the polymorphic viruses alters its signature pattern whenever it replicates.
