If disabling the file by changing the name doesn’t work, try moving it to a different location where Windows can’t find it on startup. If that works, then delete it. Alternately, you may be able to delete references to it in the registry if you’re comfortable running regedit. I would definitely find a way to remove it.
BTW, it’s good practice to do what you did periodically to see what aps are using resources.
There are eight files beginning with those letters. I'll see if I can move the exe file.
It's interesting using Task Manager and seeing some programs using a huge amount of disk and/or memory. My son's computer goes crazy with the hard drive if he leaves it for a few minutes. It sounds like a machine gun. Touching any key stops the activity, so I must have Task Manager running before it starts that. One particular program was causing that activity. The name of the program is no longer in my memory banks.
