Customers report a message like "Dangerous page blocked" or "Bitdefender blocked this page" when visiting your site. Or you spot a Bitdefender "malicious" label on VirusTotal. Either way, a large group of potential visitors is being turned away.
Here is how Bitdefender decides a site is dangerous and how to get a false positive corrected.
Key takeaways
- Bitdefender's web protection data is used in its own products and by many partner vendors.
- Its verdicts also appear on VirusTotal.
- False positives are reported through Bitdefender's official submission form.
- Clean, well-documented requests are usually handled within a few days.
Where Bitdefender's verdict shows up
Bitdefender's URL reputation powers its antivirus suites, the TrafficLight browser extension and its business endpoint products. Its data is also licensed by other security companies and shown on VirusTotal. One listing can therefore affect visitors across many products. See our Bitdefender vendor page for more background.
Why Bitdefender flags clean websites
Typical triggers include:
- Scripts that resemble cryptominers, malvertising or drive-by downloads.
- Downloads such as installers or ZIP files that heuristics consider risky.
- Past compromises that left a listing behind after cleanup.
- Shared hosting with malicious neighbours or a recycled IP address.
How to submit a false positive to Bitdefender
Bitdefender handles website disputes through its official submission process:
- Confirm that the block is current by checking the site with a Bitdefender product or VirusTotal.
- Make sure the site is clean and note any cleanup you did.
- Use Bitdefender's false positive submission form, selecting the URL or website option.
- Provide the exact URL, a short description of the site and why you believe the verdict is wrong.
- Wait for the reply, then rescan on VirusTotal to confirm the change.
Our Bitdefender false positive removal guide explains each field of the form and what to write.
What if the block comes back?
A repeat block usually means something on the page still triggers the engine, for example a third-party ad script or a download. Remove or replace the trigger and submit again, referencing your earlier request.
Frequently asked questions
Can my visitors simply whitelist my site?
Individual users can add an exception, but that does not help new visitors. Only Bitdefender can remove the verdict for everyone.
How long does Bitdefender take to respond?
Usually between one and five working days for a complete request.
Does Bitdefender share its data with other vendors?
Yes. Its threat intelligence is licensed to partners, so a listing can appear in products that do not carry the Bitdefender name.
Do I need a Bitdefender account to report a false positive?
No. The public submission form is available to anyone.
