uninstall Avast

Hello all
I’ve tryed to uninstall avast using avastclear.exe.
since then i’ve a second boot option when starting windows asking me to chose between Windows 10 or Avast Clear Uninstall . :o :o

i’ve been in Msconfig and change the default systeme to Win 10 and delete "Avast Clear Uninstall " but as soon as i choose the “standardsatrt up option” , Avast Clear Uninstall reappear and define itself as the default system…
Some one knows how to get rid of that ?

Have you tried booting into safe mode, and running the program then?

yes i did.
but i still have the dual boot option

i guess that the initial error comes from not having save and launch av cleaner from the desktop.
this seems to prevent it from starting when in safe mode.
regards
