I have a mac and all my gmail contacts were apparently sent a link from my gmail account. I'm worried I have a virus, but I didn't think they had viruses on macs. What can I do? I sent out an email to all my contacts saying not to open it, and changed my gmail password, but if my computer has a virus my new password might not be safe either. What can I do? Could they have gotten access to all my past emails? There is nothing in my sent emails... I don't even see the spam emails I sent out.
