Goga is a trojan that is executed from a malicious Rich Text Formatted (.rtf) document. Due a security vulnerability, macros are able to execute from a template pointed by a RTF file without notification to the user in Microsoft Word.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
Detailed instructions for F-Secure security products are available in the documentation found in the Downloads section of our Home - Global site.
You may also refer to the Knowledge Base on the F-Secure Community site for further assistance.
The macro in the template drops and executes an utility that collects dial-up settings from Windows. This includes the user name and the password. This information is then sent to another web site.
The template is no longer available on the web.
Further information and a fix for the vulnerability is available from Microsoft: http://www.microsoft.com/technet/security/bulletin/MS01-028.asp
