Has anyone tried AVG 2014 with Win 8 ?
It has been suggested to me.
If I use it should I shut off defender and the windows firewall?
It appears to be a suite and most have their own firewalls.
This is the wrong forum for this kind of question, (we deal only with Virus, Spyware & Malware Removal here), and are also only capable of giving personal opinions and general information about that type of query.
You can see the opinion of one person here but in future, please address this type of query in the Windows forum where you are more likely to get "informed" information or the ideas of others who have tried AVG 2014 with Win 8, (I have neither ).
