NIS window pop

I'm sure this has been answered before but I've searched and I can't find anything. I am helping a friend whose laptop is running Windows 8. She keeps getting this window that pops up mentioning svchost.exe once we say OK, we get iexplorer.exe, and it contiunes. It's very frustrating when this windows pops up all the time. I do we disable that?

 

Thanks
