I just downloaded norton antivirus yesterday and it broke my minecraft. Launcher doesn't work, can't download new launcher. When I click on the launcher, it ties to open but the minecraft window never comes up. This is a modded client version. Appreciate any help.
You can try reinstalling Java firstly:
First, go to the Programs and Features in Control Panel (Add and Remove Programs on XP). Uninstall everything that says Java in the name. Then, go to http://java.com/en/download/manual.jsp to re-install Java.
However, it is known for Norton to break Minecraft, so if the above doesn't help, then you may wish to remove Norton.
