solved.... by me...
Nevertheless, the avast account still doesn't work well and doesn't communicate with the device, but truthfully, I don't care any longer.
Terrible avast support. After 3 days not a single reply from the avast team either on the forum or to the support request i left!!!!!!
And we are talking of mobile devices, and possible sms costs involved (115sms in 24hours!!!)
No more avast to me
