I am helping my mother and after installing windows 10, then office 2013, I download and at about 58% of install of ESET it "Loses internet connection" This happens over and over and over; I can not seem to figure out why and the only way so far to fix it is to uninstall ESET and leave the desktop vulnerable.... WHATS UP???? I have used EST for YEARSSSSSSSSSSSSSs and never had this issue.
