More Information

W32/VB-DZE is a worm for the Windows platform.

W32/VB-DZE spreads by sending a link to the copy of the worm in a message using the Yahoo Instant Messenger.

When first run W32/VB-DZE copies itself to:

<Windows>\Help\Other.exe
<Windows>\dc.exe
<Windows>\inf\Other.exe
<Windows>\sviq.exe
<System>\Fun.exe
<System>\WinSit.exe
<System>\config\Win.exe

and creates the file <Windows>\wininit.ini.
