Answer 1

I have Norton Internet Security, but that doesn't seem to have stopped it. And it's goofy. It won't let me lock it by clicking its lock. The lock keeps magically coming unlocked.
Also, my computer crashes more than once a week on average.
Those two facts are related.
Norton Antivirus has a very long and illustrious reputation for mangling Mac OS X systems, sometimes to the point where a complete reinstall is necessary. Among other things, it installs kernel extensions which are known to cause kernel panics and system freezes; it contains known and documented bugs which can silently corrupt Adobe Photoshop and Adobe InDesign files, destroy a user's ability to authenticate as an administrator, and (on PPC systems) can cause Classic to stop functioning; and Symantec has on at least two occasions now released flawed .dat file updates which erroneously report certain critical Mac OS X files as "viruses." (Deleting these "viruses" causes damage to the system that in some cases renders it unbootable.)
