Avast won't enable shields nor cannot connect to my account

[REDACTED]

Hi! For the past few days I have been unable to turn on avast shields/firewall. It starts with Windows (10, up-to-date) like that.
I tried to update avast, it doesn't respond. I tried to log onto my account, but it keeps saying “Internal server errror”.
I have no problem connecting to my account through Firefox, and avast on my other PC works just fine (practically identical software configuration).

I even tried reinstalling the program completely. I have no idea what should I do next. Help, please?

Did you use aswclear ?
If not, do so and then install the latest avast version.

If you did...
What exact OS/SP ?
What exact version of avast ?
Any other security (related) software installed ? (or was there)

I did now and it worked like charm—thanks, didn't know about that application

Most AV vendors have a removal tool
