Is AVZ (Antiviral Toolkit) flagging your website or file?

If AVZ (Antiviral Toolkit) is flagging your site or a file — often as manual-toolkit suspicious/heuristic findings (not standardized labels) — it is either a real infection or a false positive. 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 AVZ (Antiviral Toolkit)

AVZ is a diagnostic toolkit by Oleg Zaitsev; report via the author site or Kaspersky support. Submit here: z-oleg.com (author site)

  1. Note that AVZ is a manual diagnostic/anti-malware toolkit, not a VirusTotal scanning engine — it produces no automatic VirusTotal verdicts.
  2. If an AVZ script flags a file as suspicious, report it via z-oleg.com.
  3. Since AVZ is often run at Kaspersky’s request, you can also raise it with Kaspersky support.
  4. Re-check with a mainstream scanner to confirm.

Good to know: Still maintained by Oleg Zaitsev (a Kaspersky employee); distributed via z-oleg.com and Kaspersky support. Never a VirusTotal scanning engine.

Step 3 — If it 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, as a USA-based WordPress security specialist who handles the cleanup and the delistings for you.

It keeps coming back — why? Because the real infection is still there. A full cleanup stops the loop.
