Which scan technique detects known malware by matching signatures in the FortiGuard Labs database?

The antivirus scan technique is designed specifically to identify known malware by matching the signatures of malicious files against a database maintained by FortiGuard Labs. This database contains a wide array of unique identifiers for various malware strains, allowing the antivirus software to effectively detect and neutralize threats. Signature matching is a fundamental method in traditional antivirus solutions, providing reliable detection based on previously recognized malware patterns.

While other scanning techniques may identify malware through different methodologies, they are not primarily focused on signature matching. For instance, behavioral scans monitor the actions of programs in real-time to detect suspicious activity rather than relying on stored signatures. Heuristic scans, on the other hand, analyze the behavior and characteristics of files in order to identify potential threats that could be similar to known malware but do not possess a signature in the database. Cloud scans leverage cloud-based resources to analyze files; however, they often incorporate multiple detection techniques, including behavioral or signature matching, but are not exclusively based on known signatures.

Therefore, the antivirus scan stands out as the option that solely utilizes the signature matching approach to detect known malware effectively.
