A couple days ago a friend alerted me that e-mails, that I had not sent, were going out to everyone in my address book as if I had sent them. The e-mails have links at the bottom presumably to entice people to buy something though I have not checked these links. I have tried scanning with Norton Internet Security as well as several free-ware antivirus suites. None of them picked up anything, except a tracking cookie, so it doesn’t seem that that method will work.
I’m hoping someone out there can tell me how I can stop this from happening and also what the vulnerability might be for those who open one of these e-mails or worse click on a link. The only thing I thought of was to terminate my yahoo e-mail account but I haven’t been able to figure out how to do that either.
Please help if you can. My account is being used to spam friends, family, and colleagues and I’d hate to mess up their computers or accounts.
