Virus ScanHASH
Computes SHA-256 / MD5 / SHA-1 of a file locally in your browser, then opens the hash on every major multi-AV scan service. Files never leave your machine — only the hash does.

Why no in-browser AV?
Modern antivirus engines run as native processes with kernel hooks. A browser tab can't load 70+ commercial scanners or run unpacking on arbitrary executables. What we can do: hash the file privately, and hand that hash to the multi-AV services that already maintain global reputation databases.
If the hash already exists in VirusTotal, you'll see the verdict instantly without uploading. If it's a new file, you can drop it into the VirusTotal UI yourself.
Frequently asked questions

Scan any file or URL across 60+ AV engines. It runs on ToolMunch's own API, so the result comes back to the page with nothing to install.
Is Online Virus Scan free to use?
Yes. Online Virus Scan is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open Online Virus Scan, do the job, and take the result — nothing is gated behind a signup form.
Where is the work done?
Online Virus Scan sends what you give it to ToolMunch's own API, does the work there, and returns the result to your browser. It is used to answer that one request — it is not sold, shared, or added to an advertising profile.
