SmartFilter Security is the best security plugin to protect your WordPress site from malicious code injections in your posts and comments.

This plugin blocks scrapers, cross-site scripting attempts, and other ill behaved bots. This is the second of three security plugins.

This WordPress plugin boosts your website's security by stopping Cross-Site Scripting (XSS) attacks. It blocks and encodes harmful characters in URLs, safely handles HTML in $_GET variables, and offers settings you can customize.
