Ryan Thanks for your response and I'm sure you're right, but all I know is what I'm experiencing. I completely erased Emac hard drive, repaired permissions and disk with disk first aid, reinstalled all system software from the original CD's, reinstalled (from scratch) a limited amount of software (photoshop and FCP) and re-updated all software via Software Update. So basically a pristine system. After reinstalling everything, everything was working including FCP. Then I got my email. The same person emailed me with the same unintended attachment. And all the email disappeared. I did not yet have Norten installed. Though I have not tried to download, FCP seems to work fine. Lynn I believe you that something is going wrong with your system, but you're wr= ong about the cause.=20=20
