Sc.exe wants to run when I reboot.

Question

When I start or restart my Windows 7 OS PC I get a box telling me that se.exe wants to make changes to my PC.
The box is the standard one you get when an application is installing.  But the strange thing is that it doesn't show that sc.exe is a Microsoft application.  the box shows unknown for source.  The pop-up is also random.  I don't get
it every time. 
What would cause sc.exe to run on its own and is it something I should be worried about?

Answer 1

Yes.. Sc is not a common file that needs to run at start up. 
I would suggest you to locate file http://www.pcandtablet.com/windows-7-tutorials/1343/how-to-disable-a-startup-entry-in-system-tray-task-bar-in-windows-7-a.html
(You may untick start up entry no harm)
By hearing a process name/filename nobody  tell whether its a virus or not.. if you suspect it should be a virus/malware what
you can do is to find the file location from above and submit this sample to  virus total.. https://www.virustotal.com/
By submitting to virus total, you can check whether it is detected by famous malware scanners..
