I have Avast Mobile Security Premium. I am attempting to activate the Anti-Theft function, and it took me to Anti-Theft Setup to give permissions. There were 3 things: 1) PIN code, n/p. 2) Permissions granted, n/p. But 3) Connect to your Avast Account will not work. when I click on that, it takes me to Avast Account and has 3 ways to log in: Google, Facebook and email. All three fail repeated efforts (ie there is no mistyping). I logged into my avast account, changing the password. Logged out, and re-logged in on my computer to be sure it was right; it is. Entry of my email in (3) and avast pw results in "Login failed, check your...". So what do I do please?
