we are developing an anti-virus, I'm trying to find out how can we tell the operating system -windows XP in this case- that our software is an anti-virus. I want that the OS recognize our software as an anti-virus and the security center list it.
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:
- Must have a standard NDA with Microsoft.
- 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.
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.
