Is Cyren (now Varist) flagging your website or file?

If Cyren (now Varist) is flagging your site or a file — often showing up as Cyren/Varist “W32/…” labels (e.g. W32/Trojan, W32/<Name>.gen), sometimes a PUA suffix — 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 Cyren (now Varist)

The Cyren engine is now run by Varist; false positives go to its dedicated intake by email. Submit here: SampleFP@avsubmit.com (email)

  1. Confirm the flag is from the Cyren/Varist engine and note the exact “W32/…” name.
  2. Zip the flagged file (optionally password “infected”) or provide the URL.
  3. Email it to SampleFP@avsubmit.com (cc support@varist.com) stating it is a false positive.
  4. Include the detection name, file hash/version, vendor/product, and why it is clean.
  5. Await reclassification and re-scan.

Good to know: Cyren Ltd. went bankrupt in 2023; its AV engine is now Varist. The old cyren.com/support URL redirects to Data443 (the wrong team for AV-engine false positives) — use the Varist mailbox.

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 Cyren (now Varist) 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.
