As an addendum to my earlier post
about Qtech's nefarious habits, I found a clause in its license that lets it reinstall itself if you use an antispyware app to remove it. The license says "Qtech may store a cookie, computer file or other unique identifier on your computer to identify you and automatically repair and reinstall the Software if any third party application attempts to delete, disable or modify the Software." That is seriously ugly behavior.
Oh, and I didn't mention this, but Grokster carries Qtech in its Adroar incarnation.
