gehört zum Programm von Uniblue SpeedUpMyPc, Prozessorauslastung zwischen 1 und 5%
It eats up processor time like a drain sucks rainwater. My PC runs critically slow, removing the sump.exe processes cures all the problems.

Programm lief im Hintergrund ohne gewollten Start; HW.
I can't get rid of sump.exe. Using a Start Up Monitor program - "Advanced Uninstaller Pro" I can choose to disable this or delete it. Neither prevents it starting up. It consumes 25 - 30 % of processor time even when the system is busy loading other programs etc. Speed Up My PC (This is their file) worked for me when the processor was 100% busy all the time, but this legacy is damned annoying. I will complain.

Received this reply from Uniblue, the author of sump.exe. I was complaining about it's persistence, but it is easy to turn off this particular tool. “Even if SpeedUpMyPC is utilizing a lot of CPU usage, this is run in lowest priority while your PC is idle. So as soon as you start running an application, the SUMP.exe CPU usage will drop down automatically. If you would like to disable this feature, please click on the 'Manage' tab, go to 'Undo changes' and select 'Speed Tools'. Then locate the 'Proactive thumbnail generator' entry and set it to OFF”
eats Ram like Pac Man
It runs as an invisible precess. It sucks up a cheunk of precessor CPU and appears not to be needed.

I was able to get rid of sump.exe by uninstalling Uniblue Speed Up My PC using Windows uninstall function in the control panel. A Norton scan of all apps running on my PC confirmed that it is gone. I've rated sump.exe as dangerous more because it consumes far more RAM than any other executable file and does exactly the opposite of what the program that installed it claims it will do, i.e., speed up your PC. It also appears to create a potential for security breaches.

Best practices for resolving sump issues

A clean and tidy computer is the key requirement for avoiding problems with sump. 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.
