Update: (October 4th, 4:30pm PST) Download.com is no longer doing this (at least, not with Paint.NET).
I just noticed that download.com updated their listing of Paint.NET to version 3.5.9. Neat. Except that now they’re wrapping it in their download manager which tries to get you to install the “StartNow” toolbar. What a bunch of **** (insert your favorite 4-letter word).
I’ve already sent them an e-mail telling them that this is a violation of the Paint.NET license and to either cease this, or to remove Paint.NET from their site.
In the meantime, I obviously recommend not downloading Paint.NET from download.com.

Update: (October 4th, 9:30am PST) I received a reply from them at 2am stating they had removed the download manager from their listing of Paint.NET v3.5.9. However, as of 9am, they have not actually done this. If you go to the Paint.NET v3.5.9 listing on download.com, it still has their spammy download manager attached to it!
