Search.yourmapsnow.com or Your Maps Now is misleading browser hijacker, that replaces default search engine and homepage in Safari, Google Chrome or Mozilla Firefox on Windows or Mac. Often, it is accompanied with browser extension or application called "Your Maps Now". This add-on sneaks in browsers and takes control over main browser settings. Of course, it installs without user permission using the deceptive tactic. After installation, user search queries are redirected to query.yourmapsnow.com and then to search.yahoo.com. This allows the hijacker to collect private browser data and share it with advertising companies. The homepage also changes to Search.yourmapsnow.com and, besides search, provides quick links to main map resources such as Google Maps and Bing Maps. Page looks similar to normal search engine page, and some users don't even see the difference until they start searching for something.

PDF Converter Hub (a.k.a. PDF Converter Hub New Tab, Search.hpdfconverterhub.com) is potentially unwanted browser extension for Google Chrome, Mozilla Firefox and Safari.

It modifies search and homepage settings in these browsers and controls them not allowing users to make changes. Hijacker sets search.hpdfconverterhub.com as default search engine, new tab and home page. However, search queries typed in the search box are redirected to search.yahoo.com, so there can be some kind of affiliation or partnership between large search provider and developer of the add-on. PDF Converter Hub also constantly offers users to subscribe to its notifications, which will lead to getting unwanted advertising as desktop notifications. Main page itself consists of toolbar, search box, informational links and shortcuts to popular shopping sites and social networks. PDF Converter Hub is promoted as convenient tool for converting various file formats to PDF and vice versa.
