Re: I get a warning that someone is trying to access, and it asks me to change my password. Is it real or a fake?
I see what you mean. That does look bad. I was thinking this could be fake but it does seem real at the same time. I am guessing you only see this message when logging in with Firefox?
Can you try to open Internet Explorer and login to your Gmail account with that? If the same message appears in Internet Explorer, I believe the threat may be real. In that case, I would change my password. But not by clicking on any links in those messages. Instead, go straight to your account settings and change the password there.
