PDFSearchz browser hijacker removal instructions
What is PDFSearchz?
PDFSearchz hijacks browsers by changing some of their settings to pdf-searchz.com (address of a fake search engine). Also, this application gathers browsing-related data. Most of the times users download and install browser hijackers unknowingly, therefore, they are categorized as potentially unwanted applications (PUAs).
Users who have installed PDFSearchz on a browser have to visit pdf-searchz.com when they open a browser, new tab and enter search queries. It is because this app is designed to promote that address by assigning it as an address a homepage, new tab and default search engine. When used as a search engine, pdf-searchz.com provides results generated by Yahoo. it redirects users to search.yahoo.com. Simply said, it does not generate its own results. In order to be able to remove pdf-searchz.com from browser settings users have to uninstall PDFSearchz first, otherwise this browser hijacker will reassign its settings after every attempt to change them. Another issue with apps of this type is that they are designed to collect data related to user's browsing habits. For example, IP addresses, geolocations, entered search queries, addresses of visited pages. Although, some browser hijackers can access (gather) confidential, sensitive details as well. The bigger issue with it is that their developers could misuse gathered information to generate revenue by selling it to third parties (potentially cyber criminals) or in other ways. Depending on how data is misused, users may become victims of identity theft, experience problems with browsing safety, online privacy, or some other issues. Therefore, it is not safe to have apps like PDFSearchz installed on a browser and/or operating system.

How did PDFSearchz install on my computer?
Very often users download and/or install browser hijackers and other potentially unwanted apps through setups of other programs - when those apps are included various download and/or installation setups as additional offers. Typically, those offers are mentioned and can be declined in their "Custom", "Advanced", or other settings. However, quite often users do not even check these settings, leaving them unchanged they allow for PUAs to be downloaded or installed together with some other, intentionally downloaded and/or installed software. This software distribution method is known as "bundling". Additionally, unwanted downloads or installations can be caused by clicking deceptive advertisements: some ads, if clicked can run scripts that are designed to cause unwanted downloads or even installations.
How to avoid installation of potentially unwanted applications?
Programs and files should not be downloaded from unofficial websites, through Peer-to-Peer networks (torrent clients, eMule, and so on), via third party downloaders, installed through third party installers, etc. It is recommended to use only official websites and direct links as file, software download sources. Download and installation setups should be always checked for settings like "Advanced", "Manual, "Custom", it is common that they can be used to decline offers to download and/or install unwanted software. Ads that are being shown on unreliable pages should not be trusted - they can be designed to open pages that are not trustworthy or even run scripts designed to cause downloads and/or installations of unwanted apps. All unwanted, suspicious and/or unknown extensions, add-ons or plug-ins that are installed on a browser should be removed from it. Programs of this kind that are installed on the operating system should be uninstalled too.
