I tried doing a search here for this, because I'm sure others have had it, but I can't find anything. My yahoo email account is sending out bulk spam to contacts showing a link for pharmacuticals, etc. I understand this isn't a virus, but what steps should I do? The few things I've seen online say to change passwords and even email addresses. This seems pretty extreme, others said it only lasts a few days, and they move on. What should I do?
