Emsisoft flagged my website — how removal works
CATALOG ENTRY VERIFIED 2026-09-21
Emsisoft is an antivirus URL-reputation system: its verdict on a domain reaches everyone who runs that product, and it surfaces through multi-engine scanners such as VirusTotal, where other products and firewalls read it. It accepts website false-positive reports by email request. unflagdomain sends that request for you as part of a €39 dispatch; Emsisoft reviews the site itself and decides on its own schedule.

What Emsisoft is
Emsisoft's Web Protection and Browser Security extension block URLs from Emsisoft's own host list; false positives are reported to its lab.
What a Emsisoft flag looks like
A block inside the antivirus or its browser extension when a visitor opens the site, and a 'Malicious' or 'Phishing' line under this engine's name on VirusTotal and the free checkers that re-display it.
Why clean sites end up flagged here
- A past compromise — an injected redirect, spam pages, a phishing directory — that the engine recorded and has not re-scanned since the cleanup.
- A file hosted on the site (an installer, an archive) that matched a signature, which flags the URL that served it.
- A verdict copied from another engine's feed, so the flag appears here days after the original source.
- A genuinely clean page that the engine's heuristics read as suspicious: obfuscated JavaScript, a login form, a redirect chain.
How a removal request reaches Emsisoft
This vendor accepts a website false-positive report by email at an address it publishes in its own documentation. The message must be plain text, come from an address at the affected domain or a contact the vendor can verify, and state the URL, what was found, what was removed and when.
The general procedure — clean, verify from outside, one specific request, wait for the re-check — is in the complete removal guide, with the checklist of what every request must contain.
What unflagdomain does for this vendor
When a scan shows this vendor flagging your domain, a separately written plain-text request goes out to it in the dispatch, with your address as Reply-To, so the vendor's answer lands in your inbox. If the address bounces, another working contact is looked for and the request re-sent.
This is one of 133 vendors in the catalog. A scan shows which of them flag a domain right now; the €39 dispatch covers every one that does.
