For most AV programs it is required to use a specific uninstaller for a complete removal of the AV program. I found this list of uninstallers somewhere (I do not even remember where) and thought it would be useful to place it into this tutorial section.
Update: I just learned that the list was compiled by fredvries. And there is even more at this link.

I am glad you guys may find some use for it. But let me again point out that I did not personally compile the list. Someone had posted it a while ago somewhere in some other context - could have been Corinne. But that post had long disappeared from the radar screen and I thought it would be ashame if the list did not get more use. I use it in my teachings at the computer club.

Thanks guys for reminding me where the list originated because I did not remember. But I just thought it might be handy in our tutorial section. And I did not Google it, that's for sure.
