Obsolete soft. key keeps poping in

Obsolte software key HiDownload HKLM\Software\HiDownload keeps popping in every time, even though I delete the key form CCleaner and Registry manually, it just keeps coming back. Does anyone have the same problem? Please help me. Thank you for your time and cooperation. P.S. I installed and reinstalled HiDownload couple of times, but nothing seems to be working. Thanks again.

What is HiDownload?

I presume it's this rridgley
