Hi I am having a specific virus problem. This software is the only thing I can find that removes it or even detects it. I would like to scan several machines I have but the Windows 10 machines all have this error regardless of manufacturer Dell, Asus, or HP. The disk opens up the environment fine from the DVD and is able to scan the available drives. The problem is that some of the drives I want to scan are not available due to the fact that they are not mounted. It gives me this message Unable to mount drive run c:> shutdown /s /t 0 I tried this and it did not work The message is sometimes there and sometimes not. It depends on if the Windows session shut down correctly. As I write this message I ran this and it worked. But several times on my machine and my sisters it would not load properly. Has anyone experienced this and how did you remedy it.
