What is the primary purpose of querying the File Reputation Service?

The primary purpose of querying the File Reputation Service is to confirm malware identity. This service assesses files based on their reputation, which is built from a combination of factors including community feedback, heuristics, and historical data on known threats. By querying this service, security solutions can evaluate whether a specific file is potentially malicious, thus helping in identifying and mitigating threats effectively.

In the context of cybersecurity, confirming the identity of malware is crucial for responding appropriately. If a file is found to be harmful based on its reputation, the security system can take predefined actions, such as quarantining the file, notifying the user, or blocking its execution.

The other options do not serve the purpose of the File Reputation Service. Recovering deleted files is related to data recovery processes, while performing system diagnostics focuses on evaluating the performance and health of system components. Improving internet speed involves network optimization, which is unrelated to the threat identification and file evaluation function of the File Reputation Service.
