Why has the default home page of my web browser been changed to https://www.broadcom.com/support/security-center ?

Symantec Endpoint Protection [SEP] has the ability to combat homepage hijackers. When the homepage of a SEP client's browser has been redirected to an undesired site by a malicious infection, SEP will change the homepage as part of its remediation. As there is no way of determining what the computer's original homepage was, a default of https://www.broadcom.com/support/security-center is used unless otherwise configured.

You can specify the URL to use as the home page when the managed Symantec Endpoint Protection client repairs a security risk that hijacked a browser home page. By default if a Security Risk has hijacked the default home page for your web browser, Symantec Endpoint Protection will change it to https://www.broadcom.com/support/security-center to protect you. You can change this setting in the Symantec Endpoint Protection Management (SEPM) console.

To accomplish this:

1. Login to the SEPM
2. Select the Policies button
3. Edit your Antivirus and Antispyware policy
4. Select Miscellaneous in the Antivirus and Antispyware Policy window
5. Under Internet Browser Protection set the URL to something of your preference
6. Click OK to save the settings.
