E-mail being used for spam – What to do?
A few days ago I started getting a ton of “Mailer Daemon” emails. Now, in my “Sent” box, there are a bunch of “No Subject” emails to people in my address book. I have also gotten a few autoresponder messages from the people the emails were sent to, including WhiteHouse.gov. What can I do here?
You seem to have a spam virus .
