Hi,Sorry for the lack of info, I am new to all this. No!, don't run, I'm a fast learner. I wasn't sure what all you needed, so I took a guess. Here goes:
Envy HP allinone, touchscreen, running Win 8 (yuk) 
intel core i3-2130 cpu, 3.40 GHZ, 3400 MHZ, 2 core
memory- 3.2/3.7 GB
Ram-4.00 GB
System type-x64-based pc
Okay, when the box pops up, no matter where I am, it says word for word,
"Scripted diagnostics nature host has stopped working".
"A problem caused the program to stop working correctly.
windows will close the program and notify you if a solution is available."
It pops up every 15 minutes and I click, close program.
I'm wondering if this program is important to my computer running right?
If so, how do I fix the program?
I just followed instructions from here, yesterday, to get rid of sweetpacks. So I did a deep scan with malwarebites
and got rid of a lot of pups and some trojans and (yay!) sweetpacks. Also windows never finds a solution for anything.
If I have to do what you sent me, I know what command prompt is but what is meant with elevated?
Hope to hear from you :bubbles:oops!
