Windows 7 says I have no antvirus while Avast is running wonderfully.
Why is this and how can I fix this.
This happens to me once in a while. I reboot and the warning goes away.
If this is a problem with your Security Center not recognizing Avast, you may want to see this thread for help: http://forum.avast.com/index.php?topic=23457.0.
Otherwise, can you be more specific with your problem?
