Wierd sound when avast boot on startup

Hi ther, does anybody know why Avast is making the error noise from Windows when the pC is booting and avast is starting up. It was doing that before I format and right after I install avast, it does it again!

Anybody know?

It’s getting annoying

From avast?
I really doubt, are you sure?
Into Windows Sounds applet of Control Panel you should see (and change) all sounds related to avast.

Thank you for your reply. It is from Windows from the sound critical stop but it happen after Avast boot. Do you know where I can find the log for windows error cause Avast is blank?
Thank you
