Solved Calendar, SkyDrive, Photos, Messaging crash on launch

Hi

These 4 apps - Calendar, SkyDrive, Photos and Messaging crash on launching them almost always. I saw the Applications log and it redirected me to the TWinUI/Operational Log. In that log, it says Access Denied. What do I do? Please give me a solution which doesn't need me to refresh. Thanks

This problem has started around 1 week back.

Problem is antivirus. If you use kaspersky, these apps are in untrusted folder, just move them to trusted folder in application control
