I have similar problem. I tried to create USB disk, I formatted 16GB USB stick to FAT32, NTFS - nothing happens … The I tried to create ISO image in folder - same here - folder is empty - same as USB stick. So what is the problem?
Same problem here,
After donwloading quite a lot of bytes creation of rescue medium (USB) stops at about 40 %
I think, Avast people should have a look at this.
I use Windows 7 64bit
