Somehow someone hacked my email account and now all of my contact list is being sent spam emails that look like they are from me. Everyone keeps receiving an email from my email address that has a blank subject line, when you open it it is only a link. If you click the link it takes you to Canadian Health Care Mall, an online drug store that sell things like Viagra and Cialis. I have no idea how to make this stop. I have Norton and I don't know how this happened. Any info is greatly appreciated.
