I am geting at least 50 emails per day containing the W32.Swen@mm virus. Either they cliam to be updates from Microsoft or "returned mail". So far, my Norton Anti virus has caught and deleted all of them. However, it is slowing everything down just receiving, scanning and deleting the viruses. I know the return addresses are no good, but is there some way to trace these back from the message header? I am sure that someone I know has this on their computer and may not even know it. I sent an email to Symantec last week asking about this but never got any answer. Thanks.
