SuperPDFSearch browser hijacker removal instructions
What is SuperPDFSearch?
Usually, when users have their browsers hijacked by browser hijackers, they are forced to visit addresses they did not intend to visit. It is because apps of this type change certain browser's settings, usually to promote some fake search engine. SuperPDFSearch changes settings to superpdfsearch.com. It is very likely that SuperPDFSearch gathers browsing data (or other information) as well. It is noteworthy that most users download and install browser hijackers unintentionally. For this reason, SuperPDFSearch and other apps of its kind are called potentially unwanted applications (PUAs).
SuperPDFSearch promotes the superpdfsearch.com address by assigning it as the address of the homepage, new tab, and default search engine: it opens superpdfsearch.com when users open a browser, new tab, or enter search queries into the browser's URL bar. Superpdfsearch.com is a fake search engine because after detecting its user's geolocation, it redirects to search.yahoo.com or bing.com (via search.onlinebars.xyz). In other words, the search engine that SuperPDFSearch promotes is designed to show results generated by Yahoo or Bing. It is important to mention that the superpdfsearch.com address can be changed to any other (preferred) address only when the SuperPDFSearch browser hijacker is no longer installed on a browser. It is because most browser hijackers are designed to prevent users from reverting changes that were made by them.
Furthermore, SuperPDFSearch browser hijacker may collect personal browsing data (e.g., addresses of visited pages, entered search queries, Internet Protocol Addresses, geolocations) or even personal information about users in order to sell it later or monetize it in another way. Third parties who could buy gathered information may be cybercriminals. Depending on collected information, it could be misused to steal identities, accounts, and for other malicious purposes. Therefore, it is never really safe to have a browser hijacker installed on a browser or the operating system.

More examples of apps like SuperPDFSearch (browser hijackers) are PDFSearchly, Dong page, and BestSearchConverter. Things that most browser hijackers have in common is that they are advertised as useful, legitimate apps but are not actually useful and designed to force users to visit addresses that they would not visit by themselves. It is noteworthy that fake search engines that browser hijackers promote can show misleading results and include deceptive ads among their results.
How did SuperPDFSearch install on my computer?
In some cases, potentially unwanted apps are distributed through deceptive advertisements by designing them to cause unwanted downloads or installations by executing certain scripts. Users unknowingly download or install unwanted apps by clicking those ads. Although, most PUAs are distributed by bundling them together with other, mainly free programs (by including PUAs in downloaders, installers as optional downloads, installs). Users agree with unwanted offers when they finish downloads, installations without checking and changing "Custom", "Advanced" settings, or without unticking checkboxes that downloaders, installers often have.
How to avoid installation of potentially unwanted applications?
Always pay attention when downloading and installing software because the software downloader or installer can include unwanted offers (typically, optional downloads and installations can be declined using "Advanced", "Custom", "Manual" settings or by unticking available checkboxes). Use reliable sources for downloading files and programs, such as official pages and direct links. Do not use third party downloaders, installers, unofficial websites, Peer-to-Peer networks (e.g., torrent clients, eMule), and so on. Also, avoid clicking on ads while visiting questionable, suspicious websites. By clicking those ads users could allow them to open other untrustworthy pages or even to download, install unwanted applications. Do not keep any unwanted apps (extensions, plug-ins, add-ons) installed on a browser or programs of this kind installed on the operating system. If your computer is already infected with SuperPDFSearch, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
