Why does my ZA suddenly think taskswitch.exe is a problem? Two months ago I began getting a warning that taskswitch.exe may be monitoring keystrokes and mouse movements. This alarm only appears upon start-up or reboot. I have been blocking it. This utility seems to be a standard part of windows. Should I simply permanently allow it?
