Just uninstall them on app manager.If it can't be uninstall. open x terminal and type the ff code.

root
apt-get purge <thenameofhteprogramyouwantotdelete>

reminder if you have to have "rootsh" installed to apply the root command.

If still doesn't work Restore your last backup file from the backup app.

And if STILL doesn't uninstall. reflash your device.
