In addition to or instead of the error message, you may see a blank box with the following title:

C:\Windows\Start Menu\Programs\Startup\Kak.hta



CAUSE
This behavior is caused by the Wscript/Kak.worm virus, which uses ActiveX and Windows Scripting Host to spread by using Microsoft Outlook Express 5.



RESOLUTION
There are two methods to remove this virus.

Method 1
Obtain and install an antivirus program that can detect and remove the virus.

Method 2
Manually remove the virus:  Quit Outlook Express. Install the Microsoft scriptlet.typelib/Eyedog security update. Information about this update is available at the following Microsoft Web site:

ftp://ftp.microsoft.com/peropsys/IE/IE-Public/Fixes/usa/Eyedog-fix/x86/q240308.exe

 Search for all files named Kak.hta and Kak.htm and delete them. Delete the default e-mail message signature in Outlook Express. To do this, start Outlook Express, click Options on the Tools menu, click the Signatures tab, click the default signature, and then click Remove to delete the signature. Delete any messages that may contain the embedded script.</ol>
