Why?: Yahoo! serve their scripts from the same URL as their ads.

Older Norton Versions

These instructions are for Norton Internet Security 2005. For previous versions, see My Original Page.

The Fix

If that didn't work

First, ensure you cleared the temporary files ("Delete Files...").

If it doesn't work, Yahoo! may have changed their URLs, or it is different for your local server. You can still fix it, by looking into the logs.

Learning from the Logs

I produced this fix by reading the logs, and seeing what Norton was doing.

In Norton Internet Security, Choose "Norton Antispam" on the left. Click on "Statistics". On the right hand side, choose "View Logs".

On the left, click "Content Blocking". You will now see a list of URLs on the right, choose the yahoo.com/yimg.com ones, and you will see in the bottom pane what was blocked and why, look for the scripts that were blocked, and the reason. You can then build a rule for the URL and add the "reason" part to the permit box like above. This is the real example I used to build the rules above:

As you can see, that is the first of the rules, you will have to go into IE after you add this rule, clear temporary files, try chat again, and check with the logs to see what new has been blocked. Our only interest is with the (script) blocks.
