As its name suggests, you can supposedly login and gain quick access to your various emails with My Login Hub. However, this is not the case. My Login Hub is a browser hijacker that will attempt to commandeer your browser search and homepage. Search results from this search engine will direct you to malicious websites to get money from you or infect your computer further. It may also prevent you from changing your settings back.
My Login Hub is usually installed through bundled software without you knowing. Remove it immediately.
