I don't suggest blindly deleting the file from the program files directory and never have, yes that will remove the program but it will leave all ties attached to the now removed dll, and exe files in the system registry. There is a file that can be modified and I believe it may be the one listed above that will unhide the messenger program from the add/remove program list. Once that has been done simply use the add/remove program feature of XP and remove it and all ties to it from the system. IMHO, deleting the folder as mentioned above does more harm than good, and should never be done. Same thing goes for renaming directories. it simply isn't a clean way of resolving the issue. The out of site, out of mind, theory doesn’t really work with computers, as half the things used are out of site.
