Which version of Windows 10 ??? Regular or Insider Preview Build ???

Did you use avastclear before installing avast again ?

how do I know if I have regular or insider? sorry silly question ;D

yes I use it in safe mode

Default is regular. If you didn’t select Insider, you don’t have it.
To find your version of Windows, use the Windows Key and the R key combination.
Type: winver into the box that opens and hit OK.
You’ll see something like this:

yes this is same as my winver. so mine is insider preview build? so how can I fix this ui glitch?

@ Hellopogo2,
No, you are using the latest release of Windows 10 not an insider preview build.
I suggest you try the following:

Repair Avast:
Control Panel> Program and Features (Add/remove program)>Select Avast> Select Repair. Reboot when completed

If Repair doesn’t fix the problem, try the following:
Clean Install of Avast:
