Hello David,
What you described is Vista just doing its proper job, conflicts and
troubles will not arrive until you force the install of those programs.
Also, browse these Forums for learning what factually occurs after adding
the program (and other similar programs) that you shared.
Question for you:
Do you desire a conflict free computer, or, do you desire perpetual
conflicts while using Vista and browsing the Internet?
Vista end users that *never* add third party programs rarely ever visit
theses Forums unless their only purpose is for sharing the joy and user
friendly functionalities while using Vista.
As end users add third party programs to Vista, progressively, (user
induced) troubles and conflicts develop while using Vista.
While browsing these Forums, almost without exception, the majority of
complaints are from users that have added third party programs.

We humans are sometimes firmly creatures of habit, wrongly believing what
was needed yesterday must be needed today. XP needed third party a/v. Vista
is not XP.
