Avast not responding

[Mytenia]

Hi everyone.
Just assembled this brand new computer as a Christmas gift to myself.
Been playing with it on the holidays and everything was running fine.
Avast was working like a charm all that time.
Avast Free,minimal install + Mail and quiet mode

Came back from work today and windows tell me my computer is not secure,i check to see in avast and avast refuse to launch.Restart the computer and windows stop telling me there is a problem,but avast still cannot be launched,it's active in the background but any attempt to access it,either from the windows menu,desktop shortcut or from the systray,avast open but hand with a grey circle in the center of the screen.

Uninstalled and reinstalled,problem persist.
Booted up in Safe mode and used the uninstaller,rebooted,reinstalled,rebooted,and same thing,problem persist.
I'm kind of at a loss on what to do next.

Everything was working fine yesterday,no windows update since,any idea?

I did a repair,didnt work.
Went in safe mode,used the uninstaller,rebooted,reinstalled,didnt work.

Computer is brand new,not even 1 month old,so i told myself i would do a format since all my games are not yet installed.

Formatted the computer,fresh new windows 10 pro installed.
I install chrome,then search avast,click on the first link and install avast.

Same problem and now worst.
Avast is detected by windows security,but again wont lauch itself and hang if i try.
Worst part is on installation i was never asked for a custom install so now avast installed EVERYTHING without my consent.
So now i'm on a fresh windows with a non working antivirus that windows tell me is working fine ..... with

I install chrome,then search avast,click on the first link and install avast.

What was the link?
Did you run uninstall via  avast Uninstall Utility?

Download https://files.avast.com/iavs9x/avastclear.exe on your desktop
Start Windows in Safe Mode
Open (execute) the uninstall utility
If you installed Avast in a different folder than the default, browse for it. (Note: Be careful! The content of any folder you choose will be deleted!)
Click REMOVE
Restart your computer

you can download and install from here:

No matter what i try i can't get it to work at all,i'm out of idea now

Created a new user and try to install from it - don't work
Safe-mode avast clear then reinstall using offline link - don't work
Install in diagnostic mode - don't work
Formatted again - don't work
Reinstalled and booting before trying to open it - don't work
Reinstall and booting multiple time before opening it - don't work
Disabled desktop scaling - don't work
Had a go at different screen resolution - don't work

Just spent close to 6h of uninstalling and reinstalling it
Any insight from anyone would be welcome

I've never installed avast in a raid setup, maybe time to try using default standard install settings, install to C: drive only-no RAID?
