Frequently Asked Questions
How often should I scan my WordPress site for security issues?
Scan at least weekly for most sites. High-traffic or e-commerce sites should scan daily. Always scan after installing new plugins, updating themes, or making significant changes. Set up automated monitoring for continuous protection.
Why do different security scanners show different results?
Each scanner uses different databases and detection methods. Some focus on malware while others check configuration issues. No single tool catches everything. Using multiple scanners gives you the most complete picture of your security status.
What should I do if a scanner finds malware on my site?
First, don’t panic. Take your site offline if possible to prevent spreading infection. Restore from a clean backup if available. If not, manually remove infected files identified by the scanner. Update all passwords. Then investigate how the malware got in and fix that vulnerability.
Are free security scanners as good as paid ones?
Free scanners work well for basic checks. They detect common malware and blacklist status. Paid services typically offer deeper scanning, automatic monitoring, and cleanup assistance. For most small sites, free tools provide adequate protection when used regularly.
Can security scanners find all vulnerabilities?
No scanner catches everything. External scanners only see what’s publicly accessible. Some malware hides from detection. Server-level issues may not show up. Use scanners as one part of your security strategy along with strong passwords, updates, and secure hosting.
What does it mean if my site is blacklisted?
Blacklisting means security services flagged your site as dangerous. Google may show warnings. Browsers may block access. This usually happens after a malware infection. Clean your site completely, then request removal from each blacklist. The process varies by service.
