Protecting Yourself From The Installation is as simple as closing the application, however you cannot close it by clicking the X in the top right corner.
If you see anything like the image box (above):
Immediately press ALT + F4 (hold down ALT, then press F4)
This will close the application without invoking it.
Do Not Click ANYTHING or anywhere in the popup box.
(not even the X to close it)
The entire box itself is simply the method to install the program.
Although it appears to be a fully functional application, it is in fact waiting for you to click it.
The best method to uninstalling these is to purchase malwareBytes Antimalware Pro
