How to remove SmartPDFConverterSearch from browsers

What is SmartPDFConverterSearch?

SmartPDFConverterSearch promotes a fake search engine (smartpdfconvertersearch.com) by making changes to certain browser settings. It also collects information relating to users' browsing activities. Note that browser hijackers are categorized as potentially unwanted applications (PUAs), since users often download and install them inadvertently.

SmartPDFConverterSearch promotes smartpdfconvertersearch.com by assigning it as the homepage, new tab and default search engine.

I.e., ensures that users are forced to visit smartpdfconvertersearch.com when they open a browser, new tab, or enter search queries into the URL bar - smartpdfconvertersearch.com redirects users to search.yahoo.com and simply provides results generated by Yahoo.

I.e., it does not generate unique results and is thus fake. Fake search engines can only be removed from browser settings after uninstallation of the browser hijacker that promote them. In this case, smartpdfconvertersearch.com can be prevented from opening only when SmartPDFConverterSearch is no longer installed on the browser.

Browser hijackers also collect browsing data (e.g., geolocations, IP addresses, entered search queries, addresses of visited websites) and sensitive, personal information. Furthermore, the information can be misused to generate revenue. For example, it might be sold to third parties (potentially, cyber criminals).

These browser hijackers can thus cause issues relating to online privacy, browsing safety, and even identity theft.

There are many browser hijackers online. Other examples are EQSearch, Spark Search and Keysite. In most cases, they are advertised as tools that improve the browsing experience, provide quick access to websites, include various features, etc. In fact, browser hijackers are useless to their regular and designed only to generate revenue for the developers.

How did SmartPDFConverterSearch install on my computer?

Unwanted downloads and installations often occur when developers distribute PUAs (including SmartPDFConverterSearch) by integrating them into the download/installation setups of other programs as "extra offers". This distribution method is known as "bundling".

The offers can be declined in "Custom", "Advanced" and other similar settings of the setups (or by unticking certain checkboxes). Many users fail to check and change these settings (or untick the checkboxes), thereby allowing PUAs to infiltrate together with the desired software.

PUAs are also downloaded and installed by clicking deceptive advertisements (usually on untrusted sites) that execute certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.

When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others).

If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately. If your computer is already infected with SmartPDFConverterSearch, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
