This is an Apple computer dll for windows that has to do with Service Discovery. iTunes installs it, as does other apple software.
Not what I'd call malware. Pretty tame shit.

I'm not sure of the outcome of this program but so far the only programs that have been removed are ones that seemed suspicious to me because not only did I not install them I don't think they contained any relevant purpose as to the operation of my pc's performance. So far I'm pleased with this cleaner's work and advise.

I have a virus ccebba93.se that freefixer could not detect. I have looked and tried quite a few anti-malware programs to fix it and so far no luck. Looks like it needs manual removal. Any recommendations? If you offer remote removal service I would take you up on that.

I have seen one-eyed cats. Don't think your "human" question is fool proof. Maybe noses, mouths or anal cavities would be more precise? :>D

Here is my 2022 view of this. It is legitimate. Okay to keep. Has been 7 years since these comments so I feel time has answered this question as has the 0 detections on every malware scan.

My Acer Aspire laptop with updated Win 7 has very heavy security. NOTHING has triggered this in 10 years except freefixer (which gave color green). Feel free to remove yours but I am KEEPING mine. NO danger.

Golf und Spielautomaten sind zwei Aktivitäten, die sehr unterschiedlich erscheinen können. Es gibt jedoch einige wichtige Verbindungen zwischen diesen beiden Arten. https://www.golfsportmagazin.de/golfnews/vermischtes/diese-automaten-spiele-wurden-vom-golfsport-inspiriert/ Golf-Slots sind ein beliebtes Genre, das Spielern die Möglichkeit bietet, sich wie ein professioneller Golfer zu fühlen.
