Removal instructions for Bronze Aid

Recommended Posts

What is Bronze Aid?

The Malwarebytes research team has determined that Bronze Aid is a browser hijacker. These so-called "hijackers" manipulate your browser(s), for example to change your startpage or searchscopes, so that the affected browser visits their site or one of their choice. This one also displays advertisements.

How do I know if my computer is effected by Bronze Aid?

This is how the first screen of the installer looks:
