Overview

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Characteristics

This virus propagates by infecting Word Documents in Microsoft WORD Versions 6.x / 7.x on Windows and Macintosh platforms. The virus consists of these macros: AUTOOPEN, FILESAVEAS, BADBOY, AUTOEXEC, FILENEW in an infected document. The virus becomes active by using Auto- and SystemMacros. All macros are encrypted using the standard Word execute-only feature. Meaning that the user is unable to edit or view the macro code.

Symptoms

On an infected system the virus deletes the FILE|TEMPLATE, TOOLS|MACRO and TOOLS|CUSTOMIZE functionality.

Each infected document will contain a text entry: KENNY-G S... for Summary|Author in FILE|PROPERTIES and GANSTA RAPPA for Summary|Keywords in FILE|PROPERTIES.

At an infected system on the 1st or 13th of a month several MessageBoxes like

;

are displayed. During the display it will set the FILE|SAVEAS password to 'gansta' . If you are affected please read "Add. Information". After setting the password two MessageBoxes like

are displayed.

Method of Infection

General Macro Virus Information

Removal

All Users :
Script,Batch,Macro and non memory-resident:
Use current engine and DAT files for detection and removal.

PE,Trojan,Internet Worm and memory resident :
Use specified engine and DAT files for detection. To remove, boot to MS-DOS mode or use a boot diskette and use the command line scanner:

Additional Windows ME/XP removal considerations

Users should not trust file icons, particularly when receiving files from others via P2P clients, IRC, email or other mediums where users can share files.

AVERT Recommended Updates :

* Office2000 Updates

* Malformed Word Document Could Enable Macro to Run Automatically (Information/Patch )

* scriptlet.typelib/Eyedog vulnerability patch

* Outlook as an email attachment security update

* Exchange 5.5 post SP3 Information Store Patch 5.5.2652.42 - this patch corrects detection issues with GroupShield

Additionally, Network Administrators can configure this update using an available tool - visit this link for more information .

It is very common for macro viruses to disable options within Office applications for example in Word, the macro protection warning commonly is disabled. After cleaning macro viruses, ensure that your previously set options are again enabled.
