System is now clean, but Avast did not detect this at all. It also had infected Adobe Reader Speed launcher (Version 7) executable and was re-installing via this exe. I am unsure of original infection vector, maybe a PDF exploit (guess) since the version of Acrobat is old. This was a customers PC, I can only recommend they upgrade that software but I doubt they will.
Latest version of Avast Free is installed and up to date.
if you think that your pc still infected…then scan with MalwareBytes

Even if you are clean this removal guide may be of interest to read ?

Oh! Sorry about the incorrect posting spot. Unfortunately I do not have a sample to submit, I had to get the system clean and back out the door. I first tried removing it manually, but it came back so I used rkill and MBAM to fully clean it.
Using RKill is what pointed me to the infected acrobat speed launcher executable.
