Used for .NET Framework stuff, if it uses to much CPU open Resource Monitor and suspend it if you terminate it it will just restart

It keeps giving me a pop up every time in IE wanting me to allow it to use a website to access an Adobe program. When I check the 'don't show message again' box and click don't allow, it pops up again. Going to try Kaspersky in Safe mode.
   
From what I know, it's safe: It's been up and running since the day I bought my computer, and no scanners have decided it to be safe. Viruses with the same name does supposedly exist, but this particular process is safe. For me it usually takes about 40MB private usage in Activity monitor.

This process should never take up more than 30% CPU! If it does than it has most likely been corruped either by fragmenting (98% of the time) or in rare cases a virus/spyware... I have been terminating it every time i see it in my task manager and my computer is running fine, better than ever actually... not sure to do from here though...
