Dear Sir,
I paid subscription for premier and as i download the software and I am not aware of that your software change my external hard disk to recovery disk in which I have lt of data now how can i get that data from hard disk please help data is very important for me.

avast doesn’t create recovery disks.

It can create a rescue disk, but it does so only if you tell it do so.
It is not done automatically.

What is telling you avast has changed the disk ?
