A suspicious email attachment, a download from a site you’ve never heard of, or a shortened link from a stranger: sometimes you just want a second opinion before you click.
VirusTotal gives you around 70 second opinions at once, for free, in your browser.
What is VirusTotal?
VirusTotal is a free online service, owned by Google, that analyses files and URLs using around 70 antivirus engines and website-reputation services. You upload a file, paste a link or search a file hash, and within seconds you see how many engines flag it and why.
Key features
Multi-engine scanning
One upload is checked by dozens of antivirus products at once. That’s more reliable than any single scanner.
URL and domain checks
Paste a link to see whether security vendors have flagged it for phishing or malware before you visit.
Hash lookup
Search by a file’s SHA-256 hash to see existing results without uploading the file itself.
How to get started with VirusTotal
- Go to virustotal.com.

Tips to get more out of it

FAQ
s VirusTotal safe to use?
Yes, but uploaded files are shared with security researchers, so don’t upload personal or confidential documents.
It says 2 of 70 flagged it. Is it a virus?
Not necessarily. A small number of detections from lesser-known engines is often a false positive. Look at which engines flagged it and what they called it.
