Delta Toolbar is browser toolbar that hijacks your search. It installs as add-on into three browsers - Google Chrome, Mozilla Firefox and Internet Explorer. Delta Toolbar replaces default search and homepage of all your browsers to search.delta-search.com or just delta-search.com.
MySearchDial Toolbar is a toolbar/hijacker. It advertises itself as "great tool to improve your search experience" however it became a real nightmare for its users due to rather sneaky techniques. It is not only installing toolbar in all three browsers, but also replaces default search and homepage to start.mysearchdial.com or search.mysearchdial.com.
