Symantec AntiVirus is the only cause of my computer crashing.
When my computer crashes and I am forced to hold down the power button for 6 seconds in order to force a shutdown, upon restart I am always presented with the Symantec "SCAN NOW" dialog box.
What seems to trigger this crash is when I switch "Apple Menue/Locations" from one setting to another (ie. ethernet to wifi)
SYSTEM DETAILS:
Mac OS 10.5.7 (same problem with 10.5.6)
MacBook Pro 2.5 Ghz Intel Core 2 Duo
SCREEN SNAP SHOTS:
Symantec AntiVirus 10.2 (17)
