Is Sangfor Engine Zero flagging your website or file?
If Sangfor Engine Zero is flagging your site or a file — often showing up as generic ML/heuristic detections (e.g. Malware.Generic-*, Suspicious.*, Trojan.* AI verdicts) — 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 Sangfor Engine Zero
Sangfor’s web form is broken; email is the reliable channel. Submit here: save@sangfor.com.cn (email)
- Confirm the detection on the file’s VirusTotal report.
- Email save@sangfor.com.cn with the VT permalink (SHA-
- , file name/version, and developer details.
- Attach the sample or a download link and state it is a false positive.
- Request whitelisting and a corrected verdict.
- Follow up after 1–2 weeks if no reply.
Good to know: Sangfor’s official submission form is broken (returns an error); email is the working route. Sangfor owns Trustlook (2018), so the engines share lineage.
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 Sangfor Engine Zero 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.
