Is Trellix / FireEye flagging your website or file?

If Trellix / FireEye is flagging your site or a file — often showing up as TrustedSource/Web Gateway “Malicious Sites” or “High Risk” reputation, miscategorized URL, Trellix/Skyhigh web block — 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:

• Run my free Is My Site Hacked? checker.
• Cross-check on VirusTotal to see every engine flagging you.

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 Trellix / FireEye

Web/URL reputation (the former McAfee TrustedSource engine) is disputed at trustedsource.org. Submit here: trustedsource.org

1. Open trustedsource.org (the Customer URL Ticketing System).
2. Select the relevant Trellix/Skyhigh product.
3. Enter your URL and view its current category and reputation.
4. Suggest the correct category/reputation and submit with justification.
5. Expect ~3–5 business days; email sites@trellix.com for bulk lists.

Good to know: FireEye’s product business became Trellix (2022); Mandiant went to Google. The site-owner-relevant URL engine is the former McAfee TrustedSource, migrated to Trellix/Skyhigh and still served at trustedsource.org.

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 Trellix / FireEye 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.
