Mouse right click restarts File Explorer in Windows 10

A poorly coded Context Menu handler might cause this symptom. I studied this item and found  extension called CppShellExtContextMenuHandler.FileContextMenuExt Class,  which is related to Context Menu.

This is part of Anti Virus Shell Extension Plug-in. Product is F-Secure Computer Security GUI.

When I disable following dll:

C:\Program Files (x86)\Saunalahti\apps\ComputerSecurity\FSGUI\FsShellExtension64.dll

the problem disappears. It might be a good idea to update this dll.
