password/uninstall question

Carelessly I discarded my aVast password for Settings. I’m told the only way to set a new password is to uninstall and reinstall aVast (Pro), but a window pops up when I try to uninstall, calling for my password. If someone is able to suggest a workaround or solution to this, I would be grateful.

  1. Download avast! Pro Antivirus: http://files.avast.com/iavs9x/avast_pro_antivirus_setup.exe
  2. Follow instructions: http://www.avast.com/uninstall-utility (Run this tool for all prior installed avast! versions…!!)
  3. Reinstall avast! with the downloaded installer from point 1.
  4. Reboot.
