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 free plugin WP DB Backup. I can restore my website if anything happens. I use my site to be scanned by WP Security Scan free plugin and asks that are suspicious-looking to be blocked by WordPress Firewall to repair hacked wordpress site.

Use a test site to check the plugin, or perhaps get a software engineer to examine it carefully. This way you'll know it is not a threat for you or your business.
