Hi, dan,
I meant from the system. As audiosrv file you copied from internet may cause harm to your computer rather than curing it. Now, as it has not allowed , it is safe. Do not copy from internet the files. It may be a excutable , but the audiosrv files would have bee a created folder from the installation.
To go to the path, Just go to start menu, type regedit and then access the path from there . It is in the Services folder in the path i mentioned in my post. Are you still having AVG. First remove it and replace with free avast, which does not quarantines window file as suspicious.
