I've merged your post back here as there really is no need for a separate thread as you are still facing the same issues and you did not respond to my previous post. Please send the information I requested to mike@zubersoft.com and I'll walk through this with you. It sounds like there is some confusion here over what versions you are using and what versions they are running, so we need to get that straightened out. There is definitely no virus. Please go to Settings->About on each device running MobileSheets, take a screenshot and send that to mike@zubersoft.com so I can see what versions you currently have on which devices. Having the Android version running on Windows does not make any sense unless it is not actually a Windows device and you are confused about that, or it's actually the Windows version of MobileSheets, in which case I'm confused why you believe it's the Android version.
