In the time that I have used the free edition I've never had this problem. Earlier this week I downloaded the latest update. This one feature that I took for granted did not work. If everything's OK it usually responds with a message "Your security is up to date." Now, nothing. What could the problem be? This was an update of my previous version, not a clean install.
Operating System:Windows XP Home Edition
