How do I access my profile to change my credit card details?
Also why am I forced to login via Google? Why is there no direct login to Avast?
Thank you
Contact avast and ask them to change the credit card details.

Forced to login with Google where ?
When I try and login to my Avast account I get offered the option to login with Facebook or Google - nothing else. I used to get right through to my account.
https://my.avast.com is working fine for me.
I can login with my email and password.
Perhaps it is a cookie on your system.
Already deleted all temporary files and tried again ?
Follow Eddy’s advice and ignore options to login via google and facebook. Also, a keyboard shortcut to run your browser in Private Mode here: Ctrl+Shift+P, which will help in deleting cookies after the end of every browser session.
[EDIT:]
Depending upon browser used for a session, another shortcut is: Ctrl+Shift+N
Ctrl+Shift+P opens up my print option.

Thanks, one of these days the’ll fix this forum. 
Firefox uses Ctrl+Shift+P for a private window, unlike some other browsers ;D

It obviously isn’t my default browser.
For me that doesn’t happen, because I have that setup to use my screen capture software ;D
