I'm using Windows ME. It happens everytime when i tried to open a document. Even if i create a new document it shows a blank page but when i type in something it closes itself. What caused it? I think it's the Trojan that effected it. I couldn't remove it from the computer. It uses Rundll32. It always pop up a page of http://www.9ringtone.com/th/index.php .
rename iexplore.exe to iexplore1.exe it stops the annoying popup.. and a bit of work need to be done on the shortcuts.
apparently the worm launch the default browser. I installed firefox, and set it as default browser, the next thing happen is it popup using firefox.. :-|
