ALCMTR.EXE - Spyware file used surreptitiously to monitor one's actions. It is not a sinister one, like remote control programs, but is being used by Realtek to gather data about customers.
I have stumbled across this database entry multiple times over the years and it really bugs me. I seriously doubt the process uses the Internet in any way and cannot phone-home. If undesired behavior had been observed, shouldn't there be more information online? If someone observed it connecting to the Internet and phoning-home, what tools were used to detect it? Did this person inspect the packets? With no source, I am almost 100% certain that the "information" in the database entry is completely incorrect. Worse, users will actually lose functionality by disabling the startup entry.
