How to make Windows 8 Messaging App work at it's best

Probably many of them would have faced the problem of Windows 8 App's being crashed or not at all  working even after the app launch. This might be a simple issue caused by Security Providers in your system.  I faced problem with "KasperSky Internet Security 2013" . Some of the Popular Apps in Windows 8 like "Mail, Messaging, People, Calender", Yahoo Mail, Engadget, iStream, were automatically put under  "Untrusted" category. This actually blocks  the apps/programs to run on full potential. Now, you need to manually check the list in Applications Activity , then select your App and change it to "Trusted" category. A sample image showing Windows 8 Facebook Touch App being changed to Trusted category from Low Restricted. Do this at your own risk , when you believe that App will not harm your security or privacy. Microsoft would have taken the licenses and other security related steps to prevent unauthorized usage or access to personal data, even  though some of the Security providers block the app usage.
