You can download it at
eXeem.com
Yes, there is apparently some adware in it, but I personally have none for some reason. Where the ads
should be, there's only white rectangles. I also scanned with Spybot S&D and Ad-Aware. Spybot only found an
empty AdCache folder in the Windows/system32 directory, and Ad-Aware found nothing. But some people have posted on Neowin that they have Cydoor (the bundled adware) right after they installed eXeem. But, there's a 'lite' version that takes out the adware; the file isn't updated to the newest public beta release though so it's still pretty buggy, but for future reference it can be found
here
[EDIT]: The 'third party' stuff is, I believe, a toolbar for IE. You can choose if you want it installed or not during installation.
