The Big green button in every Cnet page is a link to Cnet.com installer which is bundled with adware/malware but below the big green button many times there's a direct download link to the program so you can avoid all this malware.

Also you have to be logged in to cnet to be allowed to use it.

So When there's a direct link the script highlights it.
Example:
