Is F-Secure flagging your website or file?

If F-Secure is flagging your site or a file — often showing up as “Browsing Protection: Harmful webpage blocked”, DeepGuard, Trojan.TR/… — it is either a real infection or a false positive from a past issue. Here is how to get it cleared.

Step 1 — Confirm it is really a false positive

Do not request removal while malware is still present, or the flag returns. Check first:

If anything turns up, get it fully cleaned first — deleting the visible malware is not enough if a backdoor remains.

Step 2 — Report the false positive to F-Secure

Use F-Secure’s Submit a Sample form and pick the false-positive reason. Submit here: f-secure.com/en/support/submit-a-sample

  1. Open the Submit a Sample form.
  2. Select “Harmless webpage is blocked (False Positive).”
  3. Enter your site URL.
  4. Add details and your contact email.
  5. Pick the F-Secure product and submit.

Good to know: F-Secure’s business line became WithSecure in 2022 — business users submit at withsecure.com (or via Elements Security Center); consumer false positives use the f-secure.com form.

Step 3 — If the warning keeps coming back

A detection that returns after you have been cleared almost always means the infection was never fully removed — usually a backdoor in a theme file, a rogue admin user, or malware in the database. That is exactly what I fix. I am a USA-based WordPress security specialist: I remove the infection completely, submit the delisting on your behalf, and harden the site so it stays clean.

Frequently asked questions

How long does F-Secure take to clear a false positive? Once the site/file is genuinely clean and you have submitted the request, most are resolved within a few days. Submitting while still infected only restarts the clock.

It keeps coming back — why? Because the real infection (a backdoor, rogue admin, or database payload) is still there. A full cleanup stops the loop.
