What is SearchPDFConverterz?

The Malwarebytes research team has determined that SearchPDFConverterz is a search 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 particular one is a search hijacker and uses web push notifications.
