Removal Instructions


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.

Indication of Infection

If the key sequence CTRL-ALT-D is pressed, the following message is displayed:

Methods of Infection

This virus creates an infectious workbook in the XLSTART folder named "PJDAPKIR.XLS". Any workbook opened on the system will become infected. This virus hooks the Excel event handler of opening workbooks in order to run its code.



Virus Characteristics

This is a macro virus for Excel workbooks. This virus does not have a destructive payload however does contain several date activated messages.

If the macro code of this virus executes, it will create an infectious workbook in the XLSTART folder named "PJDAPKIR.XLS". This virus exists within a macro module named "SURIV_PJD_APKIR" - presumably this is some reference when spelled backwards as in "RIKPA_DJP_VIRUS".

On an infected system and while Excel is running, these key sequences are hooked and remapped:

ALT-F8, ALT-F11 - no action
CTRL-ALT-D - display message
CTRL-ALT-Z - Enable toolbar "Tools|Customize"

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.
