Summary
WordMacro/Bandung consists of six macros; AutoExec, AutoOpen, FileSave, FileSaveAs, ToolsMacro, ToolsCustomize. The virus is language dependent, ie. it is able to spread only under English version of Microsoft Word. The macros are not encrypted, but they can NOT be viewed from the Tools/Macro menu, since the virus replaces that menu command with it's own macro.
For background information on Word macro viruses, see the Concept virus.
Removal
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First, check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.

I will send the listing of this virus to whoever successfully creates the antivirus for it!!! And of course I will keep coming here to greet you with my newest viruses. Congratulations!
