Thanks for the heads up OZ 
I’ve recently installed Wordfence and I must say this is the best security plugin I’ve ever used.
WordPress › Wordfence Security
Wordfence Security is a free enterprise class security plugin that includes a firewall, virus scanning, real-time traffic with geolocation and more.
If protecting your WP from hackers, script kiddies, misbehaving bots, undesirable crawlers etc etc is important to you, check this plugin out, I highly recommend it!
It even identifies and automatically bans fake google bots
