Most of the software is clean but they do bundle 3rd party software into the installation. Often browser hijack malware that are a nightmare to get rid of. Don't click Accept on everything, pay attention to what they are asking to install, if it's not the software you want then click no. Sometimes it looks as if you cannot click but they purposefully "grey out" the button so it seems you cannot click it, but you can click NO or Disagree.
My two cents...
