Plage2000:

Infection:
The virus is transfered to your PC by opening an Email attachment. The infectionmail is masked as an answer to a written email. The text of this Email is:
"I'll try to reply as soon as possible. Take a look to the attachment and send me your opinion!"
The known names of the attachmentfile are pics.exe, images.exe, joke.exe, PsPGame.exe, newsdoc.exe, hamster.exe, tamagotxi.exe, searchURL.exe, SETUP.EXE, Card.EXE, billgt.exe, midsong.exe, s3msong.exe, docs.exe, humor.exe or fun.exe. 

Payload:
If the attachment is opened, an self-extracting WinZip-File seems to be opened. After confirmation to UnZip the file one of the following messages appear:

• "WinZip self-Extractor
  ZIP damaged: file worm name: Bad CRC number.
  Possible cause: file transfer error" 

• "WinZip self-Extractor - worm name:worm name - Application Error The exception unknown software exception (0xc00000fd) occurred in the application ...." 

In the meantime the virus copies itself under the name INETD.EXE into the Windowsdirectory. It creates a new registry entry under the key
