I reinstalled Windows 7 this morning and I see a folder called “## aswSnx private storage” on all 3 of my backup hard drives.
Is this from Avast by any chance?
And why do I have this folder on my 3 backup hard drives?
Avast 6 was installed before I reformated my computer and reinstalled Windows.

that’s Avast sandbox folder, normally hidden when Avast runs. It appears when Avast is removed. You can delete them safely.

Good to know 
Was getting worried it was put there from some kind of spyware or something nasty.
