Installed by Sandisk USB card reader

It causes a faint but constant beeping (every second or so) in headphones/speakers. (It is inaudible in speakers unless the volume is very high.) The beeping stops when I stop umonit.exe in the task manager, but it isn't listed on the startup menu. It came on a driver CD for a Genesys Logic universal card reader, & I had to uninstall the drivers to get rid of umonit.exe. The user guide that came w/ the reader says that the installation of the driver CD's contents is not necessary for Win XP/Me/2000. I don't know about Mac.
Not sure what it does, but it was installed with some utility I pulled off of IOGEAR.COM for my GUH284R to give me the Icons for the card reader. It errors out often and I just opt not to let it run. I have not uninstalled it. YET.

Mine came with an Akasa combo card reader and USB hub.

Installed by drivers for Emtec "movie cube"

Installed as part of SanDisk card readers for the special drive display icons. Poorly written as it keeps causing the driver service to run RunDLL32 to call the Activate_RunDLL function in shell32.dll
It was installed with my external USB card reader. Its a utility that watches for cards to be inserted in order to change the Icon in Windows explorer.
Disabled it and noted no effect.
Not dangerous. Comes included with 3rd party USB hardward to support notifications in Windows. Causes minor drain on resources (it's a running program in background, but shows i/o and cpu usage @ 0% during normal functioning). Rating: 99% harmless.

It was pushing the processor to 100% causing lockups, upon removal perfomance was normal again.
It causes constant CPU use, messes up mouse action. Stopped the process and the computer runs better. Will probably remove it.
It came with the Belkin Universal Media Reader. I like to see which drive (of 5) has which card in it, so for me it's useful. Doesn't cause any trouble on XP SP3

Interfered with my BH12LS35 Bluray drive; running this program caused Windows to completely lose track of the drive's existance.
It took me 4 tries to delete umonit completely, from task manager and from the explorer button. it kept popping up. on otyher forums they say that viruses piggyback on umonit

I recently built a Quad AMD system & it has been rock solid - until today. System crashed twice so finally checked “processes” and found UMonit.exe*32 running at 25% CPU. Odd my system is a 64 bit, and I have no idea how it got installed. I killed it and all’s well. I will continue to kill it after starting and if I go a few weeks with no problem I’ll try to uninstall.
I got it and it slowed my computer down. I searched for it and found it in two folders c:\windows\system32 and c:\windows\temp\common. I went to add or remove programs and couldn't see it. I renamed them and moved them to desktop and rebooted. It's not able to run now. I deleted them.

Drove services.exe PnP/EvtLog instance 50% CPU on battery power, killing umonit.exe and removing from startup solved problem
obviously it seems to do different things for different people. On my (Dell 8250, 80g, 160g, 500g, 2.4ghz., 1.2Ram, Nvidia 512 ram) it would constantly send my processor to 100% on ANY application request.
This process keeps USB flash drives locked and thus prevents "Safe Removal" from working. I had to "force eject" the flash drive, and one time this caused data corruption. UMonit.exe also prevents a lot of people from being able to image SD cards for use by Raspberry Pi (see link below for my commentary about that). I used MSCONFIG to disable it from loading and now both work fine.

Appears to have been installed as part of SanDisk's ImageMate software. Works with SanDisk's external multi-card flash media reader. Purpose of software was to display nice SD/CF/MS etc. icons in Explorer next to flash cards inserted into the reader. On my Dell running Win 7 Pro, it consumed 40% of the dual CPU. I'm uninstalling the app.
perhaps not dangerous but it slows down my PC to a crawl for 2 minutes when I plug anything into USB. Remove it - it really isn't needed at all!

Apparently was installed as part of FreeCommander XE, a Windows Explorer alternative. Uninstalling FreeCommander removed it.

Seems to be a USB Monitoring tool, (especially USB 3.0)

Best practices for resolving UMonit issues

A clean and tidy computer is the key requirement for avoiding problems with UMonit. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the UMonit.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
