Hi
I had installed anti theft on mobile, I replaced SIM card and entered pin. Then I returned my original SIM card but the previous phone number was saved in remote control on Internet. I re-installed avast but now I can't add my device on "devices". What's the problem? Last time it was very simple but now when I click on Add device - android, it shows me the download page, but I already have installed avast on computer and mobile phone.
