I back up my blogs frequently using a free plugin WP DB Backup. I will restore my blog to the last 13, if anything happens. I use my blog to be scanned by WP Security Scan plugin regularly and asks that are suspicious-looking to be blocked by WordPress Firewall to fix wordpress malware cleanup.
It is not unusual for blogs to suddenly be hacked by a random person. In fact, even entire domains get hacked. If you aren't a programmer or a programmer, there is not any way you will actually understand anything about programming languages or codes. This is the main reason why some of the people who do not know anything about codes end up if there are some methods to protect investments and their sites from such hackers, thinking.
Should you ever wish to migrate your site elsewhere, like a new hosting company, you'd be able to pull this off without a hitch, and also without having to disturb your old site until the new one was in place and ready to roll.
You can make a firewall that blocks hackers. From coming into your files, the hacker is prevented by the firewall. You must also have updated version of Apache. Upgrade your PHP. It's important that your system is filled with upgrades.
Implementing all of the above will probably take less than an hour to finish, while creating your WordPress site more immune to intrusions. Over 1 million page WordPress websites were cracked this past year, largely due to preventable safety gaps. Have yourself prepared and you're likely to be on the safe side.
