Malware & cleanup
Detect, remove, and clean up WordPress malware and compromises.

When a WordPress site is compromised, the first signs are often small: a strange redirect, a new admin user, spam links in the footer, or a Google Safe Browsing warning. Malware rarely announces itself clearly. It hides in theme files, uploads, must-use plugins, or database options and tries to stay put after a quick cleanup.
These articles cover what infections look like in practice, how reinfection loops work, and how to clean up without guessing. We focus on real patterns we see on WordPress sites: backdoors that survive password resets, modified plugin files, and malicious code that only shows for certain visitors.
If you want tools alongside the reading, Security Ninja Pro’s malware scanner helps find suspicious code, clean or whitelist findings, and check that WordPress.org plugins still match official checksums. Pair that with Cloud Firewall and login protection so you are not only cleaning after the fact.

Cleanup is only half the job. After you remove malware, change compromised passwords, review users and plugins, and confirm core and plugin files look right. Keep a known-good host or backup-plugin copy offline so you have a restore path if something was missed.
For ongoing monitoring, Pro can run scheduled scans and surface findings before visitors notice. The free plugin still gives you 50+ security tests and vulnerability checks to catch common weak spots early.
If DIY is not enough, you can hire us for malware cleanup or a fixed-price security review. Otherwise start with the malware scanner, Core Scanner, and security tests when you still have admin access, or the signs guide.
