As has been explained many (and I really mean many) times before, the phone support is not from avast but a third party.
And the only thing they are trying to do is selling you a “support deal”.
They hardly can find the power button on a system 
with small download file that then pulls other files down
What do you mean with this ? A download manager ?
then 2 times installed via ninite installer
Ninite is not for downloading/creating the avast resque disk.
