It is a third party, exe file listenng for the correct time to shut down various systems, as you will discover when you meet com.qualcom.shutdown.monitor.com shortly. Also a third party exe file from our friends at quall com.
It has been asertained that they're fairly harmless and represent a 34% security Threat Level. Which really isn't that bad compared to com. Qualcomm.atfwd.com which my friends and I believe represent a much greater threat in that it is a mirroring tool that also has full access to settings, among other things. You should find all of these cleverly tucked away in the apps hidden apps menu.
So to answer your question it is an execution file designed to help shutdown systems properly so your phone does not crash.
