Cnet claims that their downloads have been tested to be Malware-free, but obviously that is false. I have downloaded a patch from this site, and it was snagged by my anti virus immediately. Not a good site at all.
I have used Download.com for many years and it has always been a reliable source for finding and trying new programs. It is even a good source for downloading new versions of programs you have and use. Take your time and read user reviews on this site. It could save you a lot of pain in the long run. Download speeds from Download.com have always been fast.
