An inert Nimda virus has been detected in one of the Help files that is included in the Korean language version of Microsoft Application Center Test (ACT). Installing or using the Korean version of Microsoft Visual Studio .NET does not cause an infection. The risk of infection is extremely low.
The ACT Help files are a component of the Korean language versions of the Visual Studio .NET developer tool, which includes the following editions:
Visual Studio .NET Professional
Visual Studio .NET Enterprise Architect
Visual Studio .NET Enterprise Developer
The ACT Help files are also a component of Standard editions of all Microsoft developer tools, including Visual Basic .NET, Visual C++ .NET, and Visual C# .NET.
In all analyzed scenarios, Microsoft considers the chance of activating the virus to be extremely low. Detailed information about the exact location and the required steps to activate this virus are not being disclosed to protect customers from the potential actions of any malicious parties.
Customers should be advised that the virus that is contained in the file cannot be activated through standard or heavy use of Application Center Test or Visual Studio .NET. Additionally, the virus that is contained in the file cannot be distributed when you deploy projects.
Microsoft has released an update that removes the infected files from an existing installation of Visual Studio .NET. Microsoft strongly recommends that you apply the update immediately.

How to Order Replacement Media
Microsoft will automatically ship new media to volume licensing customers and Microsoft Developer Network (MSDN) customers of the Korean language version of Visual Studio .NET. Customers who purchased the Korean language version of Visual Studio .NET as a full, packaged product in the retail channels can obtain replacement media by calling (82) (2) 537-1721 in Korea.
NOTE: Replacement media is not available for the Korean language version of Visual Studio .NET Professional 60-day Trial Edition. Users of the Trial Edition must apply the available update.
If you select Local Path during Setup, the Help documentation is copied to the hard disk. When you apply the update, the infected document file is replaced. No more action is required; however, Microsoft recommends that you obtain replacement disks so that you do not have to reapply the patch with future installations. Destroy the infected CD or DVD after you receive the replacement media.
If you select Run from Source during Setup, the Help documentation remains on the CD or the DVD. The update does not replace the infected file because this file resides on the original CD or DVD. Obtain replacement disks as soon as possible, consider changing the installation type to include the Help documentation on the hard disk, and then apply the update.
Microsoft has confirmed that this is a problem in the Korean language version of the Microsoft products that are listed at the beginning of this article.
Although the chance of infection is extremely low, Microsoft always recommends that you use antivirus protection. If the virus is activated, take conventional steps to disable the virus. Virus scanning programs may not detect the inactive virus that is contained in the compressed file. Use the update that is referenced in this article to remove the infected file.
