Content Guard Pro – Database Malware Scanner, Spam Scanner & Security
Content Guard Pro is a database malware scanner and WordPress security plugin built for threats hiding in database content. It scans posts, pages, custom post types, and Gutenberg blocks for hidden SEO spam, malicious scripts, suspicious iframes, encoded payloads, and spam links that file-only scanners can miss.
Use it to find database malware after a hacked-site cleanup, catch cloaked spam before Google does, and review suspicious content before or after publishing. Content Guard Pro is built for agencies, site owners, and WordPress professionals who need visibility into the content layer of WordPress security.
What this WordPress malware scanner detects
- Hidden spam links and cloaked content using CSS tricks such as display:none, visibility:hidden, opacity:0, and font-size:0
- SEO spam injections including pharma, casino, crypto, gambling, and redirect spam
- Suspicious external scripts, iframes, and links in posts and blocks
- Obfuscated JavaScript such as eval(), fromCharCode(), Base64-encoded payloads, and data: URIs
- URL shorteners and redirectors hiding final destinations
- Cryptocurrency miner patterns
- Multi-layer encoded content that needs decoding before review
- Serialized malware in postmeta, selected options, and Elementor data when Standard Scan is enabled
Why Content Guard Pro is different
Most WordPress security plugins focus on files, login protection, firewalls, or vulnerability checks. Content Guard Pro adds database-first scanning for the places where attackers often hide content spam and SEO malware: post content, Gutenberg blocks, and deeper WordPress database fields.
It is designed to complement file scanning, not replace it.

Built for real WordPress cleanup work
Content Guard Pro is useful when: * Google flags hidden spam or SEO injections but file scans look clean * A hacked site is cleaned and you want to verify nothing malicious remains inside posts or metadata * You manage client sites and need a database malware scanner alongside your existing WordPress security stack * You want to review risky content in Gutenberg before publishing
Low-noise findings
Content Guard Pro uses confidence scoring, accessibility-aware rules, and allowlists so you can review suspicious content faster and spend less time on obvious false positives.
External services & privacy
This plugin can optionally connect to the Content Guard Pro cloud service for detection rule updates and security advisories. The plugin also supports anonymous telemetry only if you explicitly opt in. The plugin works fully offline with bundled rules.
When you opt in, the service may receive site URL, site name, WordPress version, PHP version, plugin version, and optional email preferences you explicitly submit. Anonymous telemetry may include scan counts and duration. Post content, scan results, database contents, passwords, and visitor data are never sent.
Scanning runs locally on your server.
