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.
