For me, in recent times, the plain ole Control Panel Add / Remove Programs method worked.
Just for the heck of it, I then tried running the avast Uninstall Utility and did encounter the Self Defense mechanism. I then opted to NOT run that.
I may or may not have then subsequently manually deleted any ALWIL / avast Folders I found.
Then I just installed avast (4.8) again and everything’s working fine.
