How to Scan WordPress for Malware (Free and Paid Ways)

Quick answer

To scan WordPress for malware, combine three approaches: a free remote scanner (like Google Safe Browsing or Sucuri SiteCheck) for what's publicly visible, a security plugin (Wordfence, MalCare) for a logged-in file and database scan, and a server-level file comparison against clean WordPress copies to catch hidden backdoors that remote scanners miss.

Key takeaways

  • Free remote scanners only see public symptoms, not server-side backdoors.
  • A logged-in plugin scan checks files and the database more deeply.
  • Comparing files against clean copies is the most reliable way to spot injected code.

Scanning for malware sounds simple, but a single tool rarely tells the whole story. The most reliable approach layers a few methods, because each one sees something the others miss.

1. Free remote scanners

Tools like Google Safe Browsing and Sucuri SiteCheck check your site from the outside. They're fast and free, and great for catching visible symptoms — but they only see what's public, so they miss server-side backdoors.

2. Security plugin scans

A plugin like Wordfence or MalCare scans from inside your logged-in site, checking files and the database more deeply than a remote scanner can. Run a full scan, not just the quick one.

3. Server-level file comparison

The most reliable method compares your WordPress core, theme, and plugin files against known-clean copies. Anything added or modified stands out — including obfuscated backdoors that scanners miss.

Interpreting the results

A clean remote scan doesn't mean the site is clean; it means nothing is publicly obvious. If you have real symptoms — redirects, spam, a Google warning — trust those over a "clean" quick scan.

Make it ongoing

One scan is a snapshot. Automated daily scanning catches new infections early, which is far cheaper than discovering a hack when Google blacklists you.

It's a good first check, but free remote scanners only see what's publicly visible and miss server-side backdoors. A clean result doesn't guarantee a clean site.
