The two files below were pulled down from Logitech's servers by their MyHarmony application. Their support staff uploaded File 2 to VirusTotal and they received the same result so it's definitely an "official" Logitech file. Feast your eyes on this:
File 1 (18/55 virus detections at VirusTotal)
File 2 (11/55 virus detections at VirusTotal)
They insist the files are safe but it's hard to look at those scan results and be comfortable using the application.
Is it possible their systems have been infected, or are these the worst false-positives ever?
