SmartPDFConverterSearch browser hijacker removal instructions
What is SmartPDFConverterSearch?
SmartPDFConverterSearch is designed to promote a fake search engine (the smartpdfconvertersearch.com address) by making changes in certain browser settings. Also, it is designed to collect information related to user's browsing activities. It is worthwhile to mention that browser hijackers are categorized as potentially unwanted applications (PUAs), it is because most of the times users download and install them unknowingly.
SmartPDFConverterSearch promotes smartpdfconvertersearch.com by assigning it as the address of a homepage, new tab and default search engine. In other words, makes sure that its users would visit smartpdfconvertersearch.com every time they would open a browser, new tab and enter search queries into URL bar. Smartpdfconvertersearch.com redirects users to search.yahoo.com - it provides results generated by Yahoo. In other words, it does not generate individual results and that is why it is called a fake search engine. It is common that address of a fake search engine can be removed from browser settings only after uninstallation of a browser hijacker that is designed to promote it. In this case smartpdfconvertersearch.com can be stopped from being opened on certain occasions only when SmartPDFConverterSearch is no longer installed on a browser. Another issue with browser hijackers is that thy can be designed to collect not only browsing data (e.g., geolocations, IP addresses, entered search queries, addresses of visited websites), but also sensitive, personal information. What is worse, gathered information can be misused to generate revenue, for example, it may be sold to third parties (potentially cyber criminals). Such browser hijackers can be the reason behind issues related to online privacy, browsing safety, or even identity theft.

There is a great number of various browser hijackers, some more examples are EQSearch, Spark Search and Keysite.

How did SmartPDFConverterSearch install on my computer?
It is common that apps like SmartPDFConverterSearch are distributed via download and/or installation setups of other programs. More precisely, by including them in setups as additional offers. Users can decline those offers via setup's settings like "Custom", "Advanced", or by unticking certain checkboxes. When users download and install programs without checking and changing the aforementioned settings, they download and/or install included PUAs as well. This software distribution method is known as "bundling". Sometimes unwanted downloads, installations can be caused by clicking deceptive advertisements that are designed to run certain scripts. Usually such ads appear on questionable sites.
How to avoid installation of potentially unwanted applications?
Download and installation setups should be always checked for offers to download and/or install additionally included apps. As mentioned in the previous paragraph, those offers can be declined in "Advanced", "Custom" or other settings of setups. Software (and files) should be downloaded from official, trustworthy web pages and via direct links. Third party downloaders (and installers), unofficial sites, Peer-to-Peer networks (e.g., torrent clients, eMule), or other channels, sources should not be used. It is common that they are monetized by using them as tools to distribute/promote unwanted, in some cases even malicious apps. Additionally, it is recommended not to click advertisements that appear on shady pages - they can be esigned to open other pages of this kind or even cause unwanted downloads and/or installation by running certain scripts. Unwanted apps (extension, plug-in or add-on) that are already installed on a browser should be removed. Programs of this kind that are installed on the operating system should be removed as well. If your computer is already infected with SmartPDFConverterSearch, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
