I back up my blogs frequently using a free plugin WP DB Backup. If anything happens I will always restore my website. I use my site to be scanned by WP Security Scan plugin that is free regularly and WordPress Firewall to block requests that are suspicious-looking to fix malware problem.
It's not uncommon for sites to be hacked by some random person today. Actually, even whole domains get hacked. If you are not a programmer or a developer, there's absolutely no way you will actually understand anything. This is the reason why some of the people who do not know anything end up thinking if there are some methods to protect their sites and investments from these hackers.
Exclude pages - This plugin provides a checkbox,"include this page in menus", which can be checked by default. If you uncheck it, the page will not appear in any listings of pages (which includes, and is usually restricted to, your webpage navigation menus).
You click to investigate can also create a firewall discover this info here that blocks hackers. The hacker is prevented by the firewall from coming into your own files. You must have updated version of Apache. Upgrade your PHP also. It's important that your system is always filled with upgrades.
The plugin should be updated to stay current with the latest WordPress release, play nice and have WordPress cloning and restore capabilities. The ability to clone your site (in addition to regular backups) can be useful if you ever need to do an offline website redesign, among other things.
