As far as I know, Aurora can't be removed from the Add/Remove Programs applet. The tunemypc.com software will remove aurora, but it leaves some other undesirable software behind and the uninstaller transmits info that you might not want known to DR's servers.http://www.webhelper4u.com/tnewswritigs/mypctuneupmain.htmlhttp://www.webhelper4u.com/tnewswritigs/my...eup5252005.html
I see you've posted a HijackThis log--that's the best way to go, cause most automated scanners won't touch Aurora. But some manual methods have been developed.
Also, your log thread has been answered by miekiemoes. So you're in exceptionally good hands, and should be well on your way to getting control of your PC back. Just do exactly what she asks of you--and it is a good idea to only follow her instructions while you are having your log worked on.
Best of luck to you.
