I recently installed Norton Internet Security 2011 on a Windows XP SP3 desktop. I also have a Windows 7 laptop. When I click "History", "Quarantine" or "Application Ratings" under the "Computer Protection" heading nothing happens. The same applies which I click the yellow "Settings" jump near the top. These functions do work on my laptop.
I've uninstalled the software and reinstalled it . I've also run LiveUpdate which indicated that it downloaded 23 files. But no improvement in the functionality.
What version of Norton Internet Security 2011 are you running? Open Support > About to obtain version info. Also, do you have any other real-time security products installed? When didi this started happening?
