Malware & blacklist scans your site on a schedule, daily or weekly. It checks your domain and server against public reputation lists and records every script on your key pages.

What it flags

  • Your domain or server address appearing on a blocklist, and coming off it again.
  • Scripts from a domain your site has never loaded before.
  • Obfuscated code, crypto-miner signatures and hidden iframes.
  • Third-party scripts whose contents changed at the same address.

The baseline

Your opening scan records what your pages load today as the baseline. After that, new script domains wait for review: approve the ones your team added and ignore the ones you never want alerts for.

Überprüfen Sie Ihr Verständnis

A scan flags a script from a domain nobody on the team recognises. What should you do first?

When you are listed

Fix the cause first (malware, a compromised form or account, or a shared server), then request removal from the list. The listing closes when a later scan gets a clean answer, and you get a delisting alert.
