Be aware of phishing attacks. There’s one going around on Hotmail right now. Some users are getting an email to verify their account or it will be considered old and be deleted.
Give them bad info and supposedly they will suspend or close your account. These emails are really nothing new, but usually you find them in Corporate America inboxes not free email services. Fall for this scam and you will have your login credentials swiped. As per another article on technojunkyard.net about the newest cyberworm (link at the end of this article), the people on the other end of the email are going to bank on the user using the same login info for other sites they visit (ie. bank, credit cards, personal info).
The best advice if you ever get one of these phishing emails is to delete it. There should be no one who needs your account info besides you, period. If you respond to the email, even to put in junk data to play with them, the senders now know the email address is live and will continue to send emails to it hoping that whoever reads it is gullable enough to send them the information. Just delete it and be safe. If your email software allows you to block an address or mark it junk or unsafe, do it for that email. Then you won’t even see them to accidentally respond.
