Signature-Based Detection in Antivirus Software

In this video, we explain Signature-Based Detection, the most traditional and widely used method in Antivirus and Antimalware software.

Signature-based detection works by comparing files and programs against a database of known malware signatures. Each piece of malware has a unique pattern or “digital signature,” and antivirus tools use these patterns to quickly recognize and block known threats.
