A while ago I noticed mrt.exe connecting to "Spynet" on a daily basis, always during maintenance. After a bit of research (Google to be honest) I found the reason. To disable that "feature" set the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MRT Entry name: DontReportInfectionInformation Type: REG_DWORD Value data: 1 It stopped the connection attempts on my computer. theevileagle
