I have had two WordPress blogs hacked into in the past. That was at a time when I was doing very little internet marketing, and until I found time to address the situation (months later), these sites were penalised in the search engines. They were not removed, but the rankings were reduced.
Install the how to fix hacked wordpress Firewall Plugin. This plugin investigates requests with heuristics that are simple to identify and quit obvious attacks.
Also, don't make the mistake of thinking that your hosting company will have your back as far as WordPress backups go. Not always. It's been my experience that the hosting company may or may not be doing proper backups, while they say they do. Take that kind of chance?
I don't think there's a person out there that after learning just how much of a problem WordPress hacking is that it is a fantastic idea. Something I've noticed over the years is that when it comes to securing their sites, bloggers seem to be stuck in this state.
You can make a firewall that blocks hackers from infiltrating your own blogs. The firewall prevents the hacker from coming into your files. You must have updated version of Apache. Upgrade your PHP. It is important that your system is always full of upgrades.
Just ensure which you can schedule, and you decide on a plugin that is current with release and the current version websites of WordPress, restore and clone.
