Additional details about this issue:
-----------------------------------------------------

The infected ZIP file contains a PowerPoint Presentation
within which is a slide that contains an Excel Spreadsheet.
Below is some information about the Laroux virus, which
affects the Microsoft Excel Program:

"This is a nonharmful, nondestructive concept virus.
It simply appends a macro sheet called "laroux" to
workbooks. It does not affect data or anything else
in the workbook. This is the first replicating macro
virus ever discovered in Microsoft Excel."

The information above was found off the Microsoft Website.
For additional details, please refer to:

http://support.microsoft.com/support/kb/articles/q154/1/31.asp

Unfortunately, not all Virus Detection programs will detect the presence
of this infected file. As mentioned, the virus is nonharmful and nondestructive.
Keeping it around will certainly NOT affect the performance of the Xilinx
Software, nor will it affect the use of the MS Excel tool. Removing the file
in one of the abovementioned fashions however will allow you to eliminate the
spread of the warning msg. that appears in Excel when opening subsequent documents.

We sincerely apologize for any inconvenience this may have caused you or your
customer. We will make the necessary changes to make sure that such an issue
does not arise again in the future.
