PDF Converter HD Search browser hijacker removal instructions

What is PDF Converter HD Search?

PDF Converter HD Search is a rogue application promoted for enhancing the browsing experience by providing improved search results. It is classified as a browser hijacker, as it makes unauthorized changes to browser settings to promote its associated fake search engine (feed.pdfconverterhd.com). It is also classed as a Potentially Unwanted Application (PUA), since most users install this app inadvertently. Note that PDF Converter HD Search has data tracking capabilities, which it employs to record browsing activity.

feed.pdfconverterhd.com browser hijacker

Most browser hijackers target popular browsers (Google Chrome, Mozilla Firefox, Internet Explorer, and others). After successful infiltration, they assign the homepage, default search engine, and new tab/window URL to their fake search addresses. PDF Converter HD Search promotes feed.pdfconverterhd.com in this way. Therefore, each new tab/window opened and each web search made via the URL bar all redirect to feed.pdfconverterhd.com. Most fake search engines are unable to provide unique results, and therefore simply redirect to (or cause redirection chains ending with) a legitimate search engine. This is the case with feed.pdfconverterhd.com, which redirects to search.yahoo.com. While these modifications may seem relatively minor and easy to undo, recovering the affected browser is impossible without removal of the browser hijacker. Access to the settings might even be limited or denied. If not, any user changes made are automatically reset. Nearly all browser hijackers have data tracking capabilities, including PDF Converter HD Search. By monitoring users' browsing habits (URLs visited, pages viewed, search queries, etc.), it gathers their personal information (IP addresses, geolocations, and other details). This vulnerable data is then shared with third parties (potentially, cyber criminals) intent on misusing it for financial gain. To summarize, PUAs can cause browser and system infiltration/infections and lead to serious privacy issues, financial loss, and even identity theft. To protect device integrity and user safety, remove all suspicious applications and browser extensions/plug-ins without delay.

Typically, browser hijackers share certain traits and some are even identical. MapsMyWayFreeEmail Helper App, and Easy Classifieds Tab are just some examples of apps similar to PDF Converter HD Search. These unwanted applications have a legitimate appearance and tempt users to install by offering various "useful" features. In fact, these advertised functions rarely work as promised and are often nonoperational. The only purpose of all unwanted software/content is to generate revenue for the developers. Regular users receive no value. PUAs hijack browsers, cause redirects to dubious and malicious websites, deliver intrusive ad 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 from which it can be downloaded free of charge, however, PUAs have other modes of proliferation. These applications are often spread via the download/install set-ups 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. ignoring terms, skipping steps, using pre-set options, etc.), many users increase the risk of unintentionally allowing deceptive or bundled software onto their devices. Once clicked, intrusive ads can execute scripts designed to download/install PUAs without users' permission.

How to avoid installation of potentially unwanted applications

Your content should be researched to verify its legitimacy, before downloading/installing. Use only 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 classed as untrustworthy and should not be used. Download and installation processes should be approached with caution. Read the terms, study all available options, use the "Custom/Advanced" settings and opt-out of downloading/installing additional apps, tools, features, etc. Intrusive advertisements usually seem normal and innocuous, however, they often redirect to dubious websites (e.g. adult-dating, pornography, gambling, etc.). If you experience these ads and/or redirects, 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 Malwarebytes for Windows to automatically eliminate this browser hijacker.
