I'm running Symantec Corporate Edition 8 on one of my servers. I've noticed that after a certain amount of time where they haven't scanned or updated their definitions, they're removed from the list. The only thing I can find as far as a history is to configure the logs but not the machines themselves. We have a possibility of a machine being stolen.. it was in a cubicle that no one goes into since the person who occupied it left and we're trying to tie down a time around which it disappeared. The only thing we can think of at this point is to check the virusscan logs. Unless anyone else has any better ideas?
