* \%WinDir%\%SystemDir%\drvddll.exeopenopen
* \%WinDir%\%SystemDir%\drvddll.exeopenopenopen
* \%WinDir%\%SystemDir%\drvddll.exeopenopenopenopen

It makes the following registry entry, to be activated by the next system start:

* [HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Run]
"drvddll.exe"="C:\\%WinDir%\\%SystemDir%\\drvddll.exe"

If it finds the following registry keys, it will delete them:

* [HKEY_CURRENT_USER\SOFTWARE\Microsoft\
Windows\CurrentVersion\Run\]
"My AV"=
"Zone Labs Client Ex"=
"9XHtProtect"=
"Antivirus"=
"Special Firewall Service"=
"service"=

The message sender will also be spoofed with one of the collected addresses.
