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.
I back up my blogs using a plugin WP DB Backup. If anything happens I can restore my website to the last settings. I use WP Security Scan plugin that is free to scan my site and suspicious-looking requests to be blocked by WordPress Firewall to secure your wordpress site.
Use strong passwords - Do your best to use a password, alpha-numeric, with go right here upper and lower case and special characters. Easy to remember passwords are easy to guess!
Harness Scanner goes through the files on your site database, comment and place tables. You are also notified by it for plugin names. It does not remove anything, it simply warns you for potential threats.
You may extend the plugin features with premium plugins like: Amazon S3 plugin, Members only plugin, DropShop etc.. So I think this plugin get redirected here is a fantastic option and you can use it at no cost.
Do not use wp_ as a prefix for your databases. That default is being eliminated by web hosting providers but if yours does not, adjust wp_ to anything but that.
