You can configure _AntiVirus_ to perform an automated daily scan of your theme files. If the plugin detects any suspicious code injections, it will send out a notification to a previously configured e-mail address. In case your WordPress site has been hacked, _AntiVirus_ will help you to become aware of the problem very quickly in order for you to take immediate action. ### Features * Scan for suspicious code in the theme files (daily scan with email notifications and manual scan) with an option to mark detected cases as false positive * Checksum verification for WordPress Core files * Optional: Google Safe Browsing for malware and phishing monitoring.
