Direct download links for a variety of popular Mac software products have been replaced on CNET's Download.com with installers for browser toolbars, commonly used by adware to track user browsing habits. A wide variety of Mac apps have had their download links replaced with the adware installer, including popular Mac antivirus software. At this time it is not clear if CNET had provided any prior notification to the creators of affected apps, but it appears that many of the companies were unaware that their download links had been switched to one that installed toolbars and changed web browser settings.

VersionTracker used to be heaven for Mac users! It was one of the top 5 best Mac websites on the Internet! I have net friends who work there! I used to haunt the place every day! ...Then CNET bought them.
