Hi
I received a notification in Windows the other day that there was a new version of Malwarebytes Professional and opted to download and install it. Yesterday when I started my laptop I noticed that while the Start and right-hand Taskbar icons had loaded and displayed, none of the Application Taskbar icons I had configured (by right-clicking and selecting the Pin to Taskbar option) were displaying.
I ran the Windows SFC/ Scannow and DISM utilities - neither found any errors, then uninstalled MalwareBytes and restarted, at which point my Taskbar icons were restored and displayed.
I'm running Windows 10 X64 with latest updates (Version 10.0.17134.112), and Windows Defender is active.
