As I was proceeding to empty the trash on this machine (Mac OS X version 10.6.3), a listing of thousands of items began accumulating. Trash itself shows some 237 items, many of them folders labeled as, for example "com.apple.AddressBook". I am certain that I did not send the bulk of these items to trash. Is it possible that one of the periodic Software Updates has eliminated files by sending them to Trash? Or have I picked up some malware which has sent important stuff to trash? Thanks.
Updates from cupertino will not move files into the trash can.
