My McAfee Antivirus plus was updated a couple of days ago. Ever since the update I get a message saying "Your computer is at risk". The reason for the risk is that the Windows firewall is purposely turned off. I have check the "don't show an alert when firewall is off" box but continue to get the message. How do I get rid of the message? I have several accounts and this is happening with all of them. All are Windows XP SP3.
