Some of the settings became passive ! Why?

1.Protection during pre-downloading,

2.Auto-Protect,

3.Removable Media Scan

When I check the settings, I recognized that these three features were set to passive. I did not do it. How it happened ?Pls look at the attached two screen shots. Pls tell me how I can set them active again ? and pls tell me why this happened ? Pls note that I have re-started the PC several times. But nothing changed. Rgds.
