PC Shields Overview

Shields constantly monitor activity while you surf the Internet and work on your computer, protecting your computer from malware and viruses. As you surf Internet sites, you could be targeted for a drive-by download, where an unwanted program launches and silently installs on your computer as you view pages. We recommend you keep all shields enabled. For more information, see Changing Shield Settings.

Shields run in the background without disrupting your work.

• If a shield detects an item that it classifies as a potential threat or does not recognize, it displays an alert. The alert asks if you want to continue or block the site. Do one of the following:
  • If you recognize the file name and you are purposely downloading it, for example, you were in the process of downloading a new toolbar for your browser, click Unblock page and continue .
  • If you were not trying to download anything, you should click Go back to safety
  • If you feel that the shield is alerting you to a page that is not high risk, then you can click the Request Review button.

For more information on all of these options, see Managing Web Threats.
