My computer keeps telling me to activate my personal copy of security center. it says it is not active. I turned on the security service center but it shows its not active. I keep getting pop ups about viruses and my firewall and bad things. it says my security system is on now but not active. It says i need to pay for it but i already have it and its turned on. where do i get my activation code? Help please what do i do to get the pop up bad messages to stop? Also i have windows 7 not vista what can I do?
