After I deinstalled Norton Utilities, my desktop file started getting extremely bloated and made me lose almost all of the games and apps that were on my hard drive. :O

Luckily, I made a backup, but how can I manage to reinstall stuff, especially when everything goes back to "Application not found" after shutdown and startup?

I know there is a way to "lock" individual items, but how do you do that?

(It's running OS 8.6 btw)
