#1 Just bought new Kaspersky for 2013 ,should I uninstall 2012 before I put the 2013 disc in? #2 I have verizon dsl,when I called to say it's slowing a bit they sent me a new modem and told me to download Firefox . Firefox is faster but I cant connect to my verizon home page to check my email unless I go back into verizon internet explorer. Any ideas?? Please put into very simple terms if possible,thanks.
