With this CWS variant I very much doubt the above mentioned scans would work, due to the NT service created by the parasite. Some thing you may already know, this variant sometimes deletes important Windows files. If the user gets error messages on reboot after performing any fixes, you may have to replace one or more of the following files:
1) control.exe
2) shell.dll
3) wmplayer.exe
4) rundll32.exe
5) msconfig.exe
6) notepad.exe
You can get copies of these files from Merijn's page
here for any version of Windows. The other file sometimes deleted is HOSTS --- replace it by running the
Hoster and using "Restore Original HOSTS".
