Why not? E.g. because once you have enabled it and downloaded some 200+ megs of Nero updates, it will get wiped right before the download would be over, guess why - yeah, they bundle (optional) Ask.com toolbar.
As for Bufferzone Pro - I have downloaded it a couple of days ago. It has TeamViewer bundled - an RDP alternative, completely harmless but potentially unwanted. There. Do not enable PUP and complain afterwards.
