How do I completely uninstall mywinlocker?

So, my laptop came with a program called my “mywinlocker”. I believe I had a 60 day trial to the thing, but it wasn’t a program that I was interested in using. After that trial ended, the program stayed on my computer. Because it was taking up space and memory I wanted to delete it .

When I tried to delete it the first time I faced a ton of problems and I could not just Uninstall it. So, I went into the the program and deleted as many files associated with it as I could. But I couldn’t delete everything, so I said “screw it” and gave up.

Today I saw it’s little icon down on my task bar, and it really bothered me that my computer came with an advertisement to a program that I can’t even delete. Again, I tried to uninstall it but my only option was “Change” in the install programs list. I clicked it, and after almost uninstalling, it window pops up and says that I can’t uninstall b/c I have a few processes running. Well, I went to the task manager and ended two of the four processes. When, I click “Change” to uninstall the next time, the two on the list of “Files in use” are “MyWinLocker Service” and Windows Explorer

When I go to my task manager, under services, I find the “MyWinLocker Service” but, when I attempt to ‘Stop Service’ a window pops up that says “The operation could not be completed. Access denied.”

Does anyone understand my problem?
Can anyone help me out?
