How can I tell the "windows security center" that I'm an "antivirus"?

You have to sign an NDA to get the information. Quoth MSDN forums:

To register an antivirus product:

Must be a member of the Microsoft Virus Initiative.

OR

Must meet the following three requirements:

1. Must have a standard NDA with Microsoft.
2. Must be a member of AVPD or a member of EICAR or must sign and adhere to a code of ethics relating to malware research and malware handling.

3. Must meet independent testing requirements:

   a. If you are using your own antimalware engine, you must pass VB100 and meet at least one of the following:

   • ICSA Labs - Pass
   • West Coast Labs - Pass
   • AV-Test.de – 90% or higher
   • AV-Comparitives – 90% or higher

   b. If you are packaging an antimalware engine from another company:

   • The company who developed the engine must meet the above requirements.

In order to be able to register an AV product with Windows Security Center, you need a private API from Microsoft or, starting with Windows 10 build 1809 you need to register a Protected Service. In order to do both these things, you need to be member in the MVI.

Just for the record, a few years later now, the requirements have changed a bit.

First of all, this is the new link: https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/virus-initiative-criteria

The criteria have also changed and they are more complex.

Assuming you have a product build with a 3rd party SDK, here are the requirements to become a member:

1. Offer an antimalware or antivirus product that is one of the following:

• Your organization's own creation.
• Developed by using an SDK (engine and other components) from another MVI Partner company and your organization adds a custom UI and/or other functionality.

2. Have your own malware research team unless you build a product based on an SDK.

3. Be active and have a positive reputation in the antimalware industry. Activity can include participation in industry conferences or being reviewed in an industry standard report such as AV Comparatives, OPSWAT or Gartner.

4. Be willing to sign a non-disclosure agreement (NDA) with Microsoft.

5. Be willing to sign a program license agreement.

6. Be willing to adhere to program requirements for antimalware apps. These requirements define the behavior of antimalware apps necessary to ensure proper interaction with Windows.

7. Submit your app to Microsoft for periodic performance testing.

8. Certified through independent testing by at least one industry standard organization.

The most hard to achieve requirements are marked bold.
