just to confirm it to you, what you want to write IS a virus. if you intend your program to be executed in dos/prompt mode you will have to include some ASM in you c code to first modifie the specific sys interupts and make the program finish as a TSR(terminate and stay resident) other wise, if the program is for windows and you don't want your friend to know that it is running (eg. in the startbar or as a system icon in the tray) you will still probably have to interfear with system interupts but also make a call to a program that will be a windows app. caution. any anti-virus on you friends machine will see your program as a virus and remove it and reconfigure your systems interupt table. the other problem is how to load the program on boot. for this you could just put the name in the autoexec(not very well camaflaged) or change your systems boot sector. whatever you would like to do you are looking at a lot of work for a joke. i know that this is mainly theoretical advice but i hope it will help if you still fancy the idea and come across problems with the ASM please send me a mail and i will try to help as much as pos. tim ____________________________________________________________ Do You Yahoo!?
