Some users in Russian sub-forum found a bug between avast and family safety. Microsoft support told him that this is a conflict between avast and family safety filters. The error message “kernel_mode_trap” appears only in children’s account.
He using AIS, Windows 8.1 pro x64 (another user has the same specs)
I asked him to generate support package,
file ID: ZPKQS
package name: 20150429_1853_ZPKQS_209189331.zip
