This is a Word 97 macro virus which drops a Windows script virus that infects documents when they are closed. If the virus is run under Windows 98 or Windows 2000 (NT 5) or under any Windows version running WSH (Windows Scripting Host), the virus can drop these Windows script files:
A4.VBS to the root directory
Happy.VBS to the root directory
AVM.VBS to the Windows directory
A4.VBS is not a virus. If this script is executed, it will send an e-mail message using MS Outlook (if present). The message is directed to a well-known person in the anti-virus industry.
Happy.VBS and AVM.VBS contain the script virus. This appending script virus will infect all .VBS files in these directories:
C:\
C:\WINDOWS
C:\WINDOWS\DESKTOP
C:\MY DOCUMENTS
C:\STARTUP
The script virus is independent of the Word Macro virus and will continue to spread even if the macro virus is disinfected, but most anti-virus software packages can clean and disinfect all affected files.
