For example www.facebook.com, now when we login, email and password is correct, but can not enter. Well be careful you might hit one of the hack program.
commonly used computer program is a key logger. Key logger widely used in the hacker world, especially in the theft of user names, passwords, as most users do not realize that the computer he used had been fitted with key logger. So when a user that is opening an e-mail, chat MIRC, YM, open a blog, go FS, FB, PB, even e-banking transfers all of which use user name - password turns out all the activities that have been recorded by a key logger. So, after the user left it before the installer Key logger harvest user names, passwords that have been recorded. Not great. Well I suggest to you all, change passwords by using the space as much as possible. I have tried this and hack or key logger programs can not read spaces. May help
