I recently upgraded to BD Internet Security 2011 and now find that I can't temporarily disable real-time antivirus protection. When I uncheck the box on the Antivirus/Shield tab of the control panel, I get the usual prompt to choose a length of duration, but after doing so and clicking OK, I find that the check has reappeared and the message still reads, "Real-time protection is enabled."
OS: Windows XP SP3. The problem did not occur in earlier versions of BD IS (2009, 2010).
