When I view the Page Source tab, it doesn't look anything like what YVR posted. There is nothing that indicates where the email came from or lists any IP address like in the example posted.
My sister sent me one of the spam emails and it had a totally different website link in it that I got from myself. So maybe 2 separate emails were sent out. In her email, it listed 13 random people (some in my contact list and others were people I had received an email from). I ran another virus check and nothing was found.
It is just frustrating since I am very careful about clicking on unknown links or downloading suspicious files.
