Feel better now?
Installing a Toolbar without permission is UNACCEPTABLE!
It always has been a toolbar and you gave it permission the first time you installed it! What changed with the new version was that it could not be moved in Firefox and could only be moved/merged at the left in IE7, and, if you'd read the entire thread plus the sticky at the top of this section, McAfee are totally aware of it and are working on fixing it.
It is only seldom that any McAfee person reads these forums, which are mainly peer to peer support, so if you want to voice your frustration directly use the feedback form which I have mentioned on numerous occasions in this and other threads, stickies etc. etc.
By the way, it is Firefox that prevents anything being moved, so there's the challenge for the developers.
