Not quite sure where to post this so please move it if you think it is necessary.
Anyway, on some (not all) of my email addresses I am recieving emails with subjects like "Re: Hi" and "Re: Your Approval" and "Re: Your Request" making them look like responses to messages I sent. All of these contain things likie "Please confirm!" and then a document which I haven't touched, just deleted, which I'm guessing is a virus. I'm guessing it's a virus that only affects PCs and I use a mac, but all the same, where should I report this?
