Free Multi-Engine Antivirus Scanning Sites
These free multi-engine scanning services let you check suspicious files against dozens of antimalware tools at once.
Multi-engine antimalware scanning sites check uploaded files against multiple AV products simultaneously, providing different perspectives on potentially malicious artifacts.
These free services offer multi-engine scanning:
- Hybrid Analysis
- Jotti’s Malware Scan
- Kaspersky Threat Intelligence Portal
- MetaDefender Cloud
- PolySwarm
- VirScan
- VirusTotal
Before uploading, verify you’re allowed to release the file externally and consider that uploading may alert attackers to your discovery.
When dealing with a unique file in the context of a targeted attack, uploading the file to these services could reveal to the attacker that you’ve discovered their malware. If in doubt, don’t upload your file, and instead search the database of prior scans using the file’s hash.
My other lists of on-line security resources outline Automated Malware Analysis Services, Online Tools for Looking Up Potentially Malicious Websites and Blocklists of Suspected Malicious IPs and URLs.
