DevDome Malware Scanner - free WordPress malware scanner, virus scanner and malware removal
The free alternative to Wordfence, Sucuri and MalCare for scanning and removing malware in WordPress. A WordPress malware scanner for detecting malware, backdoors, malicious code, infected files and reinfection risks. It scans WordPress files and database content, quarantines threats and safely repairs trusted files from the dashboard. It does not only find infected files: it also looks for the things that bring the malware back after a cleanup (rogue admins, cron beacons, planted must-use plugins) and keeps uncertain findings separate from confirmed threats.

What it finds
- Malware and malicious code
- Backdoors and web shells
- Modified WordPress core files
- Modified plugin and theme files
- Suspicious PHP files in uploads
- Database injections and hidden spam
- Rogue administrator accounts
- Malicious WP-Cron tasks
- Must-use plugins and drop-ins
- Configuration file changes (wp-config.php, .htaccess, .user.ini)
- Files that may reinfect the site after cleanup
Features
- Scan files and database. WordPress core, every plugin and theme, uploads, must-use plugins, drop-ins and the configuration files; script and iframe injections, encoded payloads, SEO spam and hidden links in options, posts, revisions and meta.
- Find backdoors and reinfection risks. Rogue administrators, cron beacons, planted must-use plugins and drop-ins on their own tab with a Neutralize action.
- Safe malware cleanup. One click fix quarantines known malware and replaces modified core and WordPress.org plugin files with the official copy, then scans again to verify. A quarantined file is kept as a compressed, non-executable copy in the plugin's own database table and restores with one click.
- File integrity checking. Official WordPress.org checksums for core and plugins, official theme zips, a baseline and change timeline for premium and custom code.
- Severity and confidence are separate numbers. A known-signature match is 100% confidence; an entropy blob on its own is only a signal. Coverage gaps are listed and never assumed clean.
- Scheduled malware scans. Daily or weekly, in short time-boxed batches with a WP-Cron fallback; pause, resume, cancel.
- Works without an account. Every engine runs on your server. An optional free DevDome account adds 90,000+ known-malware signatures (hashes only are sent), a multi-site security dashboard and alert emails.
- Simple and Advanced views, bulk actions, search, scan history, multisite support.
- AI agents and MCP. 20 WordPress Abilities (WordPress 6.9+) covering every action: verdict, fix plan, findings, scans, one-click fix, every finding action, quarantine, logs, settings. See below.

File Changes: created, modified, quarantined and repaired WordPress files over time.
Reinfection Risks: rogue admins, malicious cron jobs, must-use plugins and drop-ins.
Malware Quarantine: quarantined files, restorable at any time.
Scan History: previous malware scans and detected threats.
Settings: optional account features, vulnerability check, scan limits and excluded paths.
AI agents and MCP (WordPress Abilities API)
Since 1.2.0, on WordPress 6.9 and newer, DevDome Malware Scanner registers the whole plugin as WordPress Abilities: 20 abilities covering every action of the screens. An AI agent or MCP client connected to the site through the official WordPress MCP Adapter discovers them automatically, so you can ask Claude, ChatGPT or Cursor "is this site infected, what would one-click fix do, mark the finding about my own plugin as a false positive and schedule weekly scans". Every ability runs under the same administrator capability as the screens (network administrator on multisite); permanent deletion is annotated destructive.
