iThemes Security uses Sucuri SiteCheck to power the malware scanning feature within the plugin. Sucuri SiteCheck uses a 10-point site check to scan your site for known malware, blacklist status, website errors and out-of-date software.
To start using Malware Scanning in iThemes Security, visit the Right Sidebar and click the Scan Homepage for Malware button.
Sucuri SiteCheck will go to work and then give you the results of the malware scan. You can also view the results from the Logs page.
Get Scheduled Malware Scanning & Email Notifications
The free version of iThemes Security allows you to manually run malware scans on the homepage of your site. With iThemes Security Pro, you can enable daily malware scanning and receive an email if a problem is found.
To turn on scheduled malware scans and email notifications in iThemes Security Pro, visit the Pro tab. From here, you can enable malware scan scheduling and select which users should get an email if an issue is found during a malware scan. You can also view the details of your malware scan report from the Logs tab.
