Which free service analyzes suspicious files and URLs for malware, often used to quickly check samples?

• A. HashMyFiles
• B. Network capture
• C. Imaging tool
• D. VirusTotal

Answer: (D)

The key idea is a centralized, free service that checks suspicious items against many antivirus and security analysis tools in one place. VirusTotal does exactly that: you can upload a file or submit a URL, and it runs the item through dozens of antivirus engines and other scanners, then returns a report showing which engines flagged it, along with metadata and sometimes additional analysis. This multi-engine view helps you quickly assess whether something is likely malware, and it aids in triage by comparing results across different scanners. HashMyFiles, by contrast, only computes hash values for files and doesn’t analyze behavior or threats. A network capture records traffic, not the file’s content or its malware status. An imaging tool creates disk images, not malware analysis.
