I back up my blogs using a plugin WP DB Backup. If anything happens I will restore my blog to the settings. I use my site to be scanned by WP Security Scan plugin and requests to be blocked by WordPress Firewall to fix malware problems free.
Hackers don't have the capability once you got these lined up for your own security, to come to a WordPress blog. You definitely can have a WordPress account especially that one that provides you big bucks from affiliate marketing.
Harness Scanner goes Home Page seeking anything suspicious through the files on your site post, comment and database tables. You are also notified by it for plugin names that are unusual. It does not remove anything, it warns you for possible threats.
Now we are getting into matters. Whenever you install WordPress, you have to edit the document config-sample.php and rename it to config.php. You want to set find more up the database details there.
Do not use wp_. Web hosting providers are removing that default now but if yours does not, adjust wp_ to anything but that.
