thanks - can you point to any good info on what the interactual software actually does to a PC , and to what exent it can screw up programs like DVDfab if it gets installed. - I tried a search here but it is not easy to seaparate the paranoia from the facts !

I read the wikipedia entry & then ran regedit to check that it was really gone, but Im resisting the urge to system restore to yesterday!
