Is there a way to Interrupt startup programs at startup rather than removing them from the folder previously?

I made a program(virus) just out of research mainly to wipe the contents of ram meaning that the computer will basically just screw up. I’m just wondering, what if a person put this program in the startup folder of a computer. Then immediatly after login the computer would screw up. There wouldn’t be any real damage to the computer…but you can’t use it. Is there a way of interrupting the program at startup rather than going in and removing it from the folder…as you mightn’t be able to get that far!
