As you may have just discovered, Norton's antivirus and Norton Utilies programs do not play nicely with SL.  Many people have had trouble with texture loading, for example, and with Ruthing. If you use Norton Anti Virus - or any of the Norton suite of utilities, try disabling them, then relogging. Norton has been known to inhibit textures from loading.  That may not solve your problem completely, but Norton may have been the trigger that started it.  It's worth a try to see, anyway.

Beyond dealing with Norton, try opening Preferences (CTRL + P  --- you can do that from your login screen without even logging in) and navigating to Graphics >> Hardware Settings to UNcheck both Enable OpenGL Vertex Buffer Objects (VBO) and HTTP Textures.  Those two features enhance texture loading efficiency for most computers, but actually have the opposite effect for some, and can cause crashes.
