Thanks for responding. I believe it was a disk image. I had just downloaded the installer and hadn't actually run it yet. I didn't want to, when I found out what the app was all about. The technician was trying to fix a Mac Mail problem and wanted to take control of my computer. He told me to just clear my downloads and that would erase the whole thing which I did, but later I noticed there was an installer icon for this program on my desktop. I don't know what you mean by "eject." There was an arrow pointing upward as I dragged it toward the trash, but it never went into the trash.
