Forgot screensaver password on a imac

[badagentx]

I'm fixing a imac for a friend and when I boot it up it starts wallzip and asks me for a password. I asked my friend and he forgot. Is there anything I can do without reinstalling OS 9? Thank you in advance. I have started it up again and found out that it is someting called wallzip locking the mac.

Have you tried booting up with Extensions disabled (boot with the Shift key held down), then removing the program?

I fixed it but thank you anyway. I just used the force quit keyboard command. It was actually a screen saver called After Dark. My friend wants to keep it but now I need to find a way to recover the password.
