Short bio

Trojan.StartPage is Malwarebytes’ generic detection name for Trojans that change the start page of a browser on the affected Windows systems.


Trojan.StartPage changes the start page of the affected browser and will keep doing so. The start page will be set to a site of the threat actors’ choosing. So the browser will open with a site that is different from the users’ preference.


Malwarebytes protects users from Trojan.StartPage by using real-time protection.
