Trojan.StartPage is a detection for Trojan horse threats that change a browser’s home page. The reasons for changing the home page vary, though it is commonly done to display advertising to the user, exploit the browser to run other threats, or to promote misleading applications.

If a Symantec antivirus product displays a detection alert for this threat, it means the computer is already protected against this threat and the Symantec product will effectively remove this threat from the computer.
