) your youtube account logon because Google has long since owned youtube, any google websites you manage, your whole fricken life basically!Here is how to avoid the hussle;
Any email you receive that ask you to open an attachment, DL a PDF to update, acknowledge, view, sign or somethings going to expire FORGET IT! don't even reply. This particular Google problem makes you think you need to logon to see the PDF and in fact you all ready are logged in or even if you are not, you will forfeit a lot of information to the losers at that simple mistake. Easy to do, all look surprisingly legit, I already seen this email in my gmail but deleted choosing not to let anyone fool me into logging, and if somethings going to expire delete, close the browser and reopen going straight to the source of the thing expiring, never go forward in the same session.
Good luck people
