Sorry to hear you're still having problems.
I wouldn't have expected Nortons to block the Java console from performing properly, but perhaps it is.
But before looking at Nortons, I have checked my own Java Console and I see that you may have to set the Java plug-in for each type of browser.
Goto Control Panel in the Start menu, and double click the Java Plug-in applet. In the Java(TM) Plug-in Control Panel click the Browser tab, and see if your browser is ticked here. If not, tick it and then click "Apply". EG, if you are using Internet Explorer, tick the Microsoft Internet Explorer box. In the "Basic" tab, make sure the "Show Java in System Tray" is not ticked. You don't want any more icons in the System Tray, (near the clock), than you already have. Close the Java control panel down.
If you are using Internet Explorer, open it up and in Tools > Internet Options, click the "Advance" tab. Scroll down until you see "java (Sun)" and make sure the box is ticked. Whilst you are there, make sure there are no boxes ticked in the Microsoft VM just below. I am given to understand that there may be security issues with the Microsoft Virtual Machine. Click "Apply"
Any changes you make under these 2 headings may bring up a message saying you must restart. Whether this is the computer or just the browser I am not sure.
Then goto the General tab, and with the green Internet globe highlighted, click the "Custom" button. Scroll down until you see Java VM. This has 3 safety settings and mine is set to Medium safety. You may have to change your settings for the Symantec site, but you can only try it and see. click OK, reboot (the computer or browser) as required, and visit the Symantec site again and see if that works.
There is a web site here;
where there is more information about Java,and where you can test your version of IE, by clicking the "Java Enabled" link on the left.
Good luck, and come back if you have any problems.
