See if this Symantec link helps you at all. It's a troubleshooting link. It will ask you questions about the version, etc. which I can't answer for it. Hopefully this will help.
when i tried to update my security (accessing web via IE first), i realized that my NSW antivirus became disabled and the email scanning has an error. when i tried to do a LiveUpdate, it gave me a message, LU#1823: live update is running in background..wait until finished..)(ZAPro says NAV is uptodate, Win Security says its been turned off). i cannot enable the antivirus or figure out the email scanning error. when i tried to access IE again, it didn't load. when i tried to end Norton, it continually says Symantec Integrator is not working. then i couldn't end any tasks or shut off my computer. also when i did try to access a website, it said i had unauthorized access.
when i tried to access the web again (via IE), it said the local connection had limited connection and might not be able to access the IE or network resources since network did not assign a network address to computer.
i have ZAPro (trial), spybot,adaware,spyware blaster. since reading so much about security issues w/IE, i downloaded mozilla. i am able to access the web w/mozilla.
any idea what is going on?
