windows not reconizing avast

All of sudden windows is saying that I don’t have virus protection. It has always recognized avast in the past…any help would be appreciated.

Which firewall are you using?
Are there many applications starting automatically with Windows?
If you boot, does the problem persist?

I use the windows firewall…I haven’t tried rebooting. Should I?
I also use spybot and ad-aware SE…

Do you mean that you do not reboot after installing? Or after the error occurred?
I think you must boot on both situations…

I didn’t reboot after the error occurred until you mentioned it. I did reboot and it fixed the problem. . . . Thank You…I’m new to this computer stuff.
