Symantec has their own support, but why go without? Try Free AVG from http://www.grisoft.com until they help you out.
I have been trying to install Norton Internet Security 2005 and it seems to install but when I get to the page where they want me to register I get this microsoft internet explorer message: Your current security settings prohibit running activex controls on this page. As a result the page may not display correctly. I can't get any further with the installation after that. What do I do? I have windows xp. I'm not sure if you need more info thanks for any help.
