PDF Converter HD Search browser hijacker removal instructions
What is PDF Converter HD Search?
PDF Converter HD Search is a rogue application, promoted as a tool for enhancing the browsing experience, by providing improved search results. It is classified as a browser hijacker, as it makes unauthorized changes to browsers' settings to promote its fake search engine - feed.pdfconverterhd.com. It is also considered to be a PUA (Potentially Unwanted Application), due to most users installing this app inadvertently. Users should note that PDF Converter HD Search has data tracking abilities, which it employs to record browsing activity.
Most browser hijackers are designed to target popular browsers (Google Chrome, Mozilla Firefox, Internet Explorer and others). After successful infiltration, they change browser's homepage, default search engine and new tab/window URLs to their fake web searcher addresses. PDF Converter HD Search promotes feed.pdfconverterhd.com in this way. To elaborate, every new tab/window opened and every single web search done via the URL bar - all redirect to feed.pdfconverterhd.com. Most fake search engines are unable to provide search results, therefore they redirect to (or cause redirection chains ending with) a legitimate search engine. This is the case with feed.pdfconverterhd.com, it redirects to search.yahoo.com. While these alterations may seem relatively minor and easy to undo, without removal of the browser hijacker recovering the affected browser is impossible. Access to the settings can be limited or denied, if not - then every user changes made are automatically reset. Nearly all browser hijackers have data tracking abilities, PDF Converter HD Search is no different. By monitoring users' browsing habits (URLs visited, pages viewed, search queries, etc.), it gathers their personal information (IP addresses, geolocations and real-life personal details). This vulnerable data is then shared with third parties (potentially, cyber criminals), intent on misusing it for financial gain. To summarize, PUAs can not only cause browser and system infiltrations/infections, but also lead to serious privacy issues, financial losses and even identity theft. To protect device integrity and user safety all suspicious applications and browser extensions/plug-ins must be removed without delay.

Typically, browser hijackers share certain traits, some are even identical. MapsMyWayFree, Email Helper App, Easy Classifieds Tab are a few examples of apps similar to PDF Converter HD Search. In fact, all PUAs tend to be similar. These unwanted applications are designed to have a legitimate appearance and to tempt users into installation by offering various "useful" features. However, these advertised functions rarely work as promised and often are outright nonoperational. The only goal of all undesirable content is to generate revenue for its developers; to users it has no real value. PUAs hijack browsers, cause redirects to unreliable and malicious websites, deliver intrusive advert campaigns (pop-ups, banners, surveys, etc.) and collect private data.
How did PDF Converter HD Search install on my computer?
PDF Converter HD Search has several promotional websites, where it can be downloaded for free. However, PUAs have other modes of proliferation as well. These applications are often spread via download/install setups of other software. This deceptive marketing method of packing regular programs with unwanted or malicious content is called "bundling". By rushing though the download/installation processes (e.g. by ignoring terms, skipping steps, using pre-set options, etc.) - users increase the risk of unintentionally allowing deceptive or bundled software onto devices. Once clicked, intrusive advertisements can execute scripts, designed to download/install PUAs, without user permission.
How to avoid installation of potentially unwanted applications?
Desired content should always be researched to verify its legitimacy, before downloading/installing it. It is highly recommended to only use official and verified download channels. P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting sites, third party downloaders and other similar sources - are considered to be untrustworthy, therefore are advised against use. Download and installation processes should be approached with caution. That entails reading terms, studying all available options, using the "Custom/Advanced" settings and opting-out from downloading/installing additional apps, tools, features, etc. Intrusive advertisements usually appear ordinary and innocuous, however these ads redirect to dubious websites (e.g. adult-dating, pornography, gambling, etc.). Should users experience such adverts and/or redirects, they are strongly urged to inspect the device and immediately remove all suspect applications and/or browser extensions/plug-ins. If your computer is already infected with PDF Converter HD Search, we recommend running a scan with Spyhunter for Windows to automatically eliminate this browser hijacker.
