Trend AV+ keeps going off and on on its own.
We're noticing this happening on 2 PCs today. It seems to be related to it trying (and failing?) to install a program update over and over again. How do we manually force this update?

This reply was created from a merged topic originally titled The tmumh service failed to start.

In event log > system there is a recurring error "The tmumh service failed to start due to the following error:
A device attached to the system is not functioning."

TMUMH is Trend Micro User Mode Hooking. There are no device errors in device manager. How can I fix this? thanks

We've merge this post to an existing conversation since the issue might due to the same reason. Thank you for letting us know that a clean reinstall fixed your "Trend AV+ keeps going off and on" issue. After the reinstall, are you still seeing the "The tmumh service failed to start" error?
