Guardio is a malicious program. It spams me continually on adware popups that have never posed a threat to my computer, and it is not removable by uninstalling it. It is invisible, not seen in my downloads or anywhere else I've tried to find and it and remove it from my perfectly protected computer.. User's recommendation: Don't buy it. don't click on it, don't even consider doing anything but clicking the x to ignore it. Yet it will continue to spam you, even after doing that.
