Download.com is now wrapping downloads with their own installer.
I just tried a download of my product and I find it really sleazy the way they wrapped it. By default they install a toolbar, change the user's default search engine to Bing, and change the user's home page to MSN.
I wonder how Microsoft feels about being associated with such a sleazy activity which acts directly against the interests of developers.
They have a FAQ page here: http://cnet-upload.custhelp.com/app/answers/detail/a_id/2064
