This just happened to my friend yesterday when I told him to install VLC. I think he may have clicked an ad instead of the first search result. I saw three pages for different add-ons and toolbars with several pre-checked checkboxes apiece. After unchecking and clicking through it just exited (hopefully) and launched the VLC install program.
