High CPU - Google Chrome - Kjdnrppeguj.exe

Pease help. What is this? High CPU - Google Chrome - Kjdnrppeguj.exe 

It is chewing up CPU and I cannot figure out how to remove it. Google Chrome is not listed in our Programs, but tracked it to this file extension (proper terminology??)

C:\Users\StPio\AppData\LocalLow\Sun\Uvuimvjssd\Sjqmjphigdrn

Am running Windows Vista Bus. 32 bit version

Have Norton 360.

Thank you.
