With Symantec Endpoint Protection you cannot block advertisements which show up in your browsers. There are many browser plugins that provide such features.

The add does not look like originating from the website itself ( - please check the enabled and running addins in the browser - possible one of them is loading the ads.

Agreed. If you look closely it says "Ads not by this site".

Browser Intrusion Prevention can help stop malicious attacks coming in via supported browsers, but for general ad-blocking... I'd also agree that there are some good browser-specific ad blocking plug-ins/add-ons out there.

Here is the link to download hardened ADC policy.

Article: Hardening Symantec Endpoint Protection (SEP) with an Application and Device Control Policy to increase security

This is important point from the list:

4. Prevents Internet Explorer (IE) and Firefox from writing code to WINDIR and Program Files, including subdirectories, also prevents Internet Explorer from launching code except in WINDIR and Program Files

Apart from this,

Use the latest version of explorer.

Use the latest service pack with latest microsoft patches.

Update third party software if there any.

You're better off using an add-in for the specific browser type. Firefox and Chrome have some good ones.

SEP will only block websites/links. Advertisements use a bit different coding for this.

Please click the "Mark as solution" link at bottom left on the post that best answers your question. This will benefit admins looking for a solution to the same problem.
