I have a very large address book (5GB) and all my contacts are receiving an email three times a day from me with a strange link to a nowhere page. I have a sbcglobal.net account but I use Outlook exclusively to send and receive emails. I have run my norton anti-virus, increased my windows firewall, adware software, etc to no avail. Each tell me my computer is clean with no problems. The address book that is sending the emails is Outlook. There are no contacts in the sbcglobal.net account. sbcglobal.net uses yahoo.com so the problem doesn't seem to be with yahoo. This is a new laptop with windows7. Can someone please tell me how to stop this nighmare? My friends and business associates are screaming with all my junk in their inbox. i have changed the password and have a complicated to specification password. I have run out of software to run and places to check for problems. I need help fast! Thanks for your quick response.
