The installer contains OpenCandy but you can download a portable zip file here without bundling such advertising program.
Infected with: Adware:Win32/OpenCandy
Don't download the program directly from this site, it is bundled with adware. The adware free download is only available from sourceforge: http://sourceforge.net/projects/pdfsam/files/
