No need to start a new topic, just continue with the other one that you have already.
No topics are closed, but they do warn that it is over 60 days old, etc. when you try to post. The reason for this is that avast versions change.
Also your question isn't really related to this subject as you don't have to disable the self defence module to uninstall avast using the windows control panel, add remove programs; you do if you try to run the uninstall utility (which has also changed in almost a year since this topic started) from windows normal mode.
Nor is it the self-defence module that creates any conflict, that is down to the low level drivers.
