My Windows 8 Start Menu Tiles open, then immediately close again.

It happens with the apps like weather and news. I saw where some have said it is Avast (in 2012). How can I fix it? This is a direct install on a brand new system, not an upgrade.

i assume you removed any factory installed AV before installing avast? ... and used that vendors removal tool
