computer at risk

Hi,

I have a problem started yesterday. Whenever I run my computer or restart it, I find the "insight protection" and "smart firewall" turned off although I switch them on evey time. And the system status is "at risk". I updated the program and tried the quick and full scan. I also run the power eraser but no use!

Is it a sign of a virus?! What should I do?

I'm using 2011 version with windows 7.

thanks..
