I did some quick googling.
Evidence suggests ieutil.exe (and iehighutil.exe) in the C:\Temporary location are copies of CGminer (bitcoin GPU mining software) installed by malware. I recommend that you run several malware scanners in safe mode. This app will cause games to slow down a lot due to the GPU being overloaded.
Removing ieutil.exe won't be enough, as the malware that installed it will still be there.
This file most likely stems from installing pirated software, as individual posts I found on Google admit they got this problem after installing pirated software.
There are some instructions to remove ieutil.exe on here:

I would still recommend you do a full scan with several malware scanners after removing this file, as there's probably other malware hiding somewhere on your system.
After removing ieutil.exe/iehighutil.exe I recommend you run Malwarebytes, SuperAntiSpyware, Spybot S&D and whatever antivirus you have installed currently (Avast by the looks of it) in safe mode to get rid of anything left over.
Next time you have a problem, I suggest you google first as it would save everyone a lot of time including yourself.
