Is to post in the CNET Spyware Forum with the link and name of the product.
Be sure you are not seeing those false positives about PUPs and the CNET downloader which are well discussed.
I downloaded the Youtube Downloader Pro from your site. Upon installation, Malwarebytes found a malicious object within. I do not know whether this is a false positive, but it's better to be safe than sorry, so I stopped installation.
I am posting this to:
a) Inform the community, and if the problem lies with CNet, allow it to be recognized and fixed.
b) if it is a false positive, discover this and proceed.
c) in the case that the problem rests with the original module, I have also informed the folks behind the Youtube Downloader web site, assuming they will pass it on to the developers.
