Avast False Positive & Blacklist Removal

Quick answer: Use the Avast false-positive form (avast.com/false-positive-file-form.php), switch it to URL mode, and enter your URL, the detection name (e.g. URL:Blacklist) and the Alert ID. This usually clears AVG too.

Is Avast flagging your website?

If Avast is warning visitors about your site — with something like URL:Blacklist, URL:Mal, URL:Phishing, URL:Scam — it means one of two things: your WordPress site really is infected, or it is a false positive left over from a problem that was already fixed. Either way, here is exactly how to get the warning removed.

Step 1 — Confirm it is really a false positive

Before you ask Avast for a review, make sure the site is actually clean. If you request removal while malware is still present, the flag comes straight back (and some vendors rate-limit repeat requests). Check it two ways:

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

Step 2 — Report the false positive to Avast

Use Avast’s false-positive form and switch it to URL mode. Submit here: avast.com/false-positive-file-form.php

  1. Open the false-positive form and toggle the type from “File” to “URL”.
  2. Enter the blocked URL, the exact detection name (e.g. URL:Blacklist) and the Alert ID from the popup.
  3. Add your email and a note that you own the site and it has been cleaned.
  4. Solve the math CAPTCHA and submit.
  5. Re-test in Avast after the engine updates (often within ~24h of confirmation).

Good to know: Avast and AVG share the same engine, so an Avast clearance usually clears AVG too. Replies can be slow — make sure you are also clean on Google Safe Browsing and VirusTotal first.

Step 3 — If the warning keeps coming back

A warning that returns after you have been delisted almost always means the infection was never fully removed — usually a backdoor in a theme file, a rogue admin user, or malware stored 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 Avast take to remove the warning? Once your site is genuinely clean and you have submitted the request, most reviews clear within a few days — see the timing note above. 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.
