I’ve purchased the Avast Pro Family Pack with three-year license. If I retire one of the PCs on which I’ve installed Avast Professional, and uninstall the software before disposing of the computer, do I recoup that license so that I can install it on a new replacement PC?
Hi…
While I have an answer I suspect would be the case, it would be best if you contacted Alwil at info@avast.com or go here for additional contact options (i.e, phone, fax or post.) 
May God Bless you!
