Hello hussam,
Please note the following:
This newsgroup is available for you to post issues and questions about the
use of the Windows Defender.
You can use it to collaborate directly with Microsoft Most Valuable
Professionals (MVPs) and other community members to get answers.
Your question would be better addressed to the Microsoft Learning Support
newsgroup where you will get a better audience for your query
Microsoft Learning Support
http://www.microsoft.com/learning/support/default.mspx
I,m sure more knowledgeable people will be along soon.
Good luck
