When Microsoft Security Essentials is installed on a computer with Windows 7, you automatically become a member of the Microsoft Security Essentials and Microsoft Defender community and grant Microsoft the ability to automatically collaborate with the your computer through Microsoft SpyNet.
Installing one of the programs adds the user automatically to a membership group which tracks program related activities and how threats are handled on the computer.
Microsoft uses the information to gain a better understanding of threats, and to improve the handling of threats for all users of the applications.
Update: Please note that Microsoft has modified how SpyNet is enabled on user systems in recent versions. You can now disable SpyNet during setup, so that you won't become a member automatically.
Besides gathering activity related information, it is also monitoring the Microsoft Security Essentials and Microsoft Defender services to make sure they are running properly on the computer system.
Microsoft Security Essentials offers two types of membership to users: basic and advanced. From basic members, SpyNet obtains information such as the origin of the software, the actions taken by Microsoft Security Essentials or the user, as well as whether the actions were helpful or not. Action in this regard means how detected files were handled, e.g. quarantined.
It also collects some personal activity information. As an advanced member, in addition to the personal information, SpyNet also sends information such as hardware or software type, IP addresses, web browser, operating system, and so on.
Though Microsoft does not use this information for any other purpose, some of you might not wish to have your personal information floating out there for others to see.
Below you will find the information that you need to get access to all of the functionality of Microsoft Security Essentials and Microsoft Defender without having to share your personal details.
