For some weeks now my computer has been sending out emails to everyone in my address...

...book. How do I stop it.? I get replies from Mailer Demon and Postmaster for ones it can't send. I have tried resetting my computer to an earlier date, but this didn't work. I thought about deleting all my cookies, but can't remember how to do it, or even if this would help. Has anyone got any advice, as I believe the emails I am sending contain a virus, and, it is driving my friends nuts. Many Thanks. Dave
