Can have AVG internet security & Norton anit virus in same computer?

Hello Katherine,

Yes, there will be conflict when you try to install our AVG program when Norton is installed already. So you need to uninstall the Norton antivirus program completely inorder to install our AVG program successfully. Thank you.

Currently I have installed Norton anti virus in my computer…can I install the AVG internet security as well. Will these 2 programs be in conflict?

Katherine, Also for your guidance have a look @ this official AVG article (http://avgclick.me/prepareforAVGinstall).
