What tools are you referring to? What is your OS? Are you running 5.0? Did you use the Avast! removal tool at http://forum.avast.com/index.php?topic=54385.0 ?-either the add/remove programs dialog in Windows or this tool should remove avast! without turning off self defense. You can turn it off manually at Summary/Settings/Troubleshooting and uncheck “Enable Avast! Self Defense Module”. You should get a pop-up asking if you really want to do that, and be able to click “yes” and turn it off. What other security software are you using? What was your previous AV and how did you unistall it. If you have a broken install, you can try removing from safe mode-F8 key during boot will get you to the menu.

@ oudave
The best option is to run the tool as suggested from safe mode - Booting into safe mode http://www.pchell.com/support/safemode.shtml
