google safe browsing notification
Hello !
When i open safari preferences in security - google safe browsing is unavailable no updates have been occurred in 1 day .
Please suggest me only the reason for its appearance .
And , please make sure, don't give methods how to remove it , as it goes itself after few days .
Any suggestions , will be highly appreciated .
A screen shot is attached for reference .
Thanks ! ( Using Mac book air El - capitan 10.11.6 )
