If you have Outlook and can use rules, try this. What I did was create a new rule, choose start from blank rule, then check messages when they arrive, with specified words in the message header, and then have it go to a folder called spam or whatever you want. You will have to click on the “specific words” which will be underlined so you can put in what to look for in the e-mail header. Then go ahead and type in W32.Sober and click on finish. I’ve managed to stop all the spam e-mails and filter them into a spam folder which I then delete every few hours.
