So you're busy shopping on the Internet when for one reason or another, you've clicked on a website link, clicked on a link in an email, etc, and this Paypal page opens. But did you check to see if it's really Paypal before attempting to put in your username and password?
While this website is an awfully good imitation of Paypal the domain name / web address is the giveaway. preinformized.com is most certainly not Paypal.
For reference, here is what Paypal's website currently looks like. Notably, until very recently Paypal did have the login on the top right of the front page of the site, however as their website is being spoofed frequently it is good to make frequent changes, like this, to help consumers differentiate their site from the fake ones.
