cdilla is a pain in the neck, but not necessarily a trojan.
I went through hoops removing it, doing HJT here, all sorts of things, but it really seems harmless.
It has to do with Macrovision protection of cd, dvd, and even some application disks.
I think I was able to get rid of it in spybot s&D startup list or someplace like that.
Spybot S&D info and advise is here:http://www.safer-networking.org/en/threats/262.html
Here's another link, but I'm not familiar with the site (siteAdvisor says is clean)http://www.auditmypc.com/freescan/readingroom/cdilla.asp
