I have the latest version of Avast Premier, which I just renewed today. Only a month ago I had no trouble creating USB rescue disks, but today, using two different USB sticks, one brand new, the operation fails with an error each time. In earlier versions it was necessary to turn off Self Defense mode to create a rescue disk, but the last one I created recently this was unnecessary. I'm running version 17.4.2294 on a Windows 7 computer.
