- Use only verified themes and plugins found in the WordPress repository or such marketplaces. - Regularly check the list of plugins and save only those that you use. Delete everything that you don't need or is inactive. - Scan your topic regularly. Ideally, you should only keep the theme you actively use. - Never use pirated themes and plugins. They usually contain malware that will infect your site. - Make sure you recognize all the plugins and themes on your site. Sometimes hackers install their own plugins and themes that have website backdoors installed. This gives them secret access to your site.
