are you still having problems deleting it? check the running processes in the background and kill the task that says MSREXE.exe and then go to your system folder and delete the file MSREXE.exe (in windows xp it is the system32 folder) you may also look for a file it may have created called msdos.exe or wondos.exe. (it changes sometimes.) I hope that helps you. P.S. just in case you don't know how to check the running processes, just press CTL+ALT+DELETE and it will show all processes running in the background
