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.

Aliases

• VBS.Story

• VBS_CHERNOBYL

Characteristics

This VBScript virus consists of a subroutine called "Chernobyl". When run, it copies itself to "c:\Windows\Story.vbs" and "c:\My Documents\Story.vbs". It sets the registry key "HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Systray" to "C:\WINDOWS\STORY.VBS" so it runs on system startup. It creates the file "c:\mirc\script.ini" which is a mIRC script which sends the story.vbs file to other users when they enter a channel an infected user is in.

Symptoms

File names mentioned above. Registry entry mentioned above.

Method of Infection

Story.vbs is received when a user enters an IRC channel. Running story.vbs will infect the system.

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

For a list of attachments blocked by the Outlook patch and a general FAQ, visit this link .
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.
