Over last mth I’ve been getting alarms when I search in Yahoo sometimes. This wk has been more frequent. (I don’t get these alarms searching Google.) My Pro version is 2014.9.0.2013 and updates complete. Use Firefox 25.0, as well.
A screenshot would be very helpful. 
what does the alarm say?.. screenshots would help
