I had a virus/adware nightmare so I tried to remove Shell$ServicesEngine with an adware remover and it completely destroyed my main windows 7 desktop machine (with a ton of settings that i want saved).
the virus kept on hijacking the browser and displayed a warning and some ads.
i had an old *Clonezilla backup of my (main) Windows 7 Desktop but it's from January.
i knew Windows was on the disk partitions 1 and 2 so i restored just those from *it (lost a few months of minor downloads and some music i tried to make).
to remove the adware i used msconfig to stop the following services from starting:
Shell$ServicesEngine
Shell$ServicesEngine_updater_service
NOTE: I decided to leave the following application in place:
Shell$ServicesEngine 3.0.0 (in Control Panel > Programs and Features)
.
so far, so good ... i thoroughly recommend using Clonezilla to backup your important machines, it was a life-saver
