Upon booting, I now receive a "Dos Promt error" Saying that a program no longer exists. I have exhausted all the references on Startup processes, looking in the Startup folder, register Keys under HKEY_CURRENT_USER\... and HKLOCAL_MACHINES\... RUN, RUNONCE, RUN ONCEEX, RUN SURVICES and RUNSERVICESONCE. Win.ini, Config.sys, Autoexec.bat, DosStart.bat plus ran a start-up manager that lists all start-up programs and I can't see where any unknown program is being asked to load. I did recently try to install a hunting type game that tried to operate in a Doss window but have removed and erased all observable traces of this program. I would guess this game maker used some form of Virus/Worm concept to load something. Any ideas?
