Fellow webmasters, I urgently need your help on this issue. Few days ago, I logged into my yahoo account only to discover that it's been hacked by some idiots. My sender's address now is 'Gtbank' instead of my email address. I also noticed that they have used my mail to send people massages that the should disclose their Gtbank account details to them.
I don't really know what to do now. I have changed my password but, when I send mails it shows 'Gtbank' instead of my email address. Please what should I do to change this?

login to your yahoo and go to Account info (it'll be @ the top) . you can change the name it displays from GTB to anything. visit http://.com/tutorials.php . they post regular tips on internet security, how hackers operate and how to protect yourself. i'll see you @ website
