re: Issues with Desktop & Taskbar Notification Area - Windows 8.1
It wasn't me but the team that keeps Malwarebytes on top of the game! Note: Malwarebytes Pro is currently a lifetime license for $29.95, but ONLY until version 2 is released -- although Marcin did say there would be ~1,000 lifetime licenses available about the time of v2 release. Version 2 is currently completing beta testing with the last update being a Release Candidate.
I agree with LilBambi's suggestion to run AdwCleaner and the Junkware Removal Tool again.
