BestPDFSearch browser hijacker removal instructions
What is BestPDFSearch?
BestPDFSearch is a browser hijacker which changes some of the browser settings to bestpdfsearch.com, address of a fake search engine. Also, apps of this type tend to be designed to collect details related to user's browsing habits (browsing data). It is common that users download and install browser hijackers inadvertently (unknowingly), for this reason they are called potentially unwanted applications (PUAs).
In most cases browser hijackers modify settings such as address of a default search engine, homepage and/or new tab. BestPDFSearch changes the aforementioned addresses to bestpdfsearch.com. The main purpose of this is to make sure that users would visit bestpdfsearch.com when they open a hijacked browser, new tab and enter search queries into URL bar. When users enter search queries into URL bar or a search bar while using a browser hijacked by BestPDFSearch they get redirected from feed.bestpdfsearch.com to search.yahoo.com. That is the main reason why a search engine which BestPDFSearch is designed to promote is called fake - it does not generate any unique results. More often than not browser hijackers do not allow users to remove a certain address from browser setting unless they uninstall them. Therefore, bestpdfsearch.com can be removed from settings when the BestPDFSearch app is no longer installed. Another problem with browser hijackers is that they can be designed to collect various data. It is common that they target IP addresses, geolocations, addresses of visited websites, entered search queries, etc. Some browser hijackers can be designed to record personal, sensitive information as well. Moreover, their developers could sell collected details to third parties (potentially cyber criminals) or misuse them to generate revenue in some another way. Therefore, users of browser hijackers can become victims of identity theft, experience problems related to browsing safety, privacy, and other issues.

There are various browser hijackers on the Internet. What most of them have in common is that they change browser settings with a purpose to promote some fake search engine. Quite often they are advertised as useful, legitimate apps that supposed to include some features, improve browsing experience, etc. However, most of them are not only useless but also can be the reason behind certain issues. More examples of similar apps (browser hijackers) are Convert Files Tools, Email Pro Hub and Ecogreen APP.
How did BestPDFSearch install on my computer?
It is common that users download and/or install programs that have "Custom", "Advanced" or other settings in their setups without changing them. The problem with it is that such setups often have various PUAs included in them as additional offers. PUAs are allowed to be downloaded and/or installed together with wanted programs when users do not decline offer to download and/or install them. This distribution method of PUAs is known as "bundling". In some cases unwanted downloads and/or installations are caused when users click shady advertisements. To be more precise, when they click ads that are designed to execute certain scripts.
How to avoid installation of potentially unwanted applications?
It is not safe to download files or programs from unofficial websites, through Peer-to-Peer networks (like torrent clients, eMule), free file hosting sites, and other channels of this kind, or install software with third party installers. The only safe way to do that is to use official pages and direct download links. Download and/or installation setups that have "Custom", "Advanced", "Manual" or other settings often contain offers to download and/or install PUAs. Therefore, those settings should be always checked. Advertisements that appear on unofficial, questionable websites can be designed to open other sites of this kind, or even download and/or install unwanted software. Therefore, it is advised not to trust such ads. If some unwanted, unknown or suspicious app is already installed on a browser, then it should be removed from it. The same applies to software of this kind that is installed on the operating system. If your computer is already infected with BestPDFSearch, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
