I ran an antivirus live update and restarted the computer. When the computer restarted, I had no internet connection. There are 3 blinking lights on my cable modem.I 've unplugged the modem and replugged it into the power in hopes of resetting it. Nothing. I am asking this question from a different computer.

if you are use a modem to connect internet then check list of things like---

1) first check your modem are work properly or not. If all lights are blink then ok or check the modem light and pc light carefuly
2) if modem are work properly then install driver which is provided by the ISP.
3) after that right click on your computer icon and goto manage , goto device manager from the left side list where you can see your new device are connected which will be show as "yellow question marks" then right clik on it get update driver.
4) update driver nd restart the computer.

your internet will be connected otherwise conatct with your intenet provider.

right click on the antivirus icon on your lower right corner of your screen and select live update. you have internet connection when doing so.

just i case there is no internet connection, you can go to a computer with internet connection and go visit the website and download the manual virus definitions from there for the antivirus you have.

live updates usually have problems like this but its very rare. try to do the manual update for your virus definitions instead. go to the website and download the latest virus definitions there. when done, you can manually update your antivirus by doing this.

do you have internet with the modem? if you do then router is not configure correctly. If you do nothave internet ask you ISP why you are not online with the modem directly.

might be your automatic update is turned off,

1) Close all Norton applications.

2) Moved file [ccWebWnd.dll]
from [C:\Program Files\Common Files\Symantec Shared\]

3) Run LiveUpdate
Type [C:\Program Files\Symantec\LiveUpdate\LUAll.exe]
into Windows Explorer Address bar and hit [Enter]

4) Restart your computer.

5) Moved file [ccWebWnd.dll]

6) Run Norton SystemWorks LiveUpdate from your Windows Start Menu.

7) Restart your computer.

Go to symantec.com, if you renewed, symantec usually sends you an upgrade to your antivirus to your email so you can update to the current antivirus software

Hi,

Did you encounter an error message when you ran the norton update? is this a licensed norton antivirus software which you bought from norton ?


Keep me posted.

Thanks
