Briefly explain your current issue(s)

Windows notifications turned off because are blocked from a third party app

Steps taken to resolve, but have been unsuccessful

Bitdefender uninstall tool, Revo uninstaller , Ccleaner

At notification Center,Windows 10, there is a message "Windows notifications turned off because are blocked from a third party app"
I know that came from Bitdefender, but the problem is I uninstall it, with BitDefender uninstall tool,then some remains with Revo Uninstaller and also with CCleaner and the problem keep remaining.Also I installed CIS and I can't get some alerts because of this.
