Please be aware that the App, unfortunately still available from the App Store, is a piece of malware/Spyware in and of itself.
This App records your every move on the internet, the apps you run on your Mac and other related data, which it then sends back home to China!
Originally this app was fashioned to look identical and have a name similar to the genuine app "Malwarebytes Anti-Malware", but Apple pulled it from the App Store for "name duplication"
Now renamed as Adware Doctor, the $4.99 app was still available at the App Store this morning.
If you do not have this App, keep it that way, but if you do, DELETE IT.
Malwarebytes Anti-Malware for Mac is highly respected and efficient. It also has a Free trial period.
