PDFt Search browser hijacker removal instructions
What is PDFt Search?
PDFt Search is a piece of rogue software, classified as a browser hijacker. Following successful installation, it makes modifications to browser settings in order to promote find.pdftsearch.net - a fake search engine. Additionally, PDFt Search add the "Managed by your organization" feature to Google Chrome browsers. Most browser hijackers spy on users' browsing activity and PDFt Search is not an exception to this. Due to the questionable techniques used to distribute PDFt Search, it is also considered to be a PUA (Potentially Unwanted Application).
Browser hijackers assign the addresses of fake web searchers as browsers' homepage, default search engine and new tab/window URLs. PDFt Search also makes these changes to browsers in order to promote find.pdftsearch.net. Hence, with this browser hijacker installed: every single search query typed into the URL bar and new browser tab/window opened - redirect to find.pdftsearch.net. Illegitimate search engines are rarely able to provide search results, so they tend to redirect to (or cause redirection chains ending with) legitimate ones. This is the case with find.pdftsearch.net as well, it redirects to the Google (google.com) search engine. Furthermore, browser hijackers can undo any changes users attempt to make to their browsers and/or restrict/deny access to the browser's settings. Therefore, recovering a hijacked browser is impossible without removing the software affecting it. As mentioned in the introduction, PDFt Search can track data as can most software of this type. Browser hijackers monitor browsing activity (URLs visited, pages viewed, search queries, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). The gathered data is then shared with and/or sold to third parties (potentially, cyber criminals), likewise seeking to misuse it for profit. In summary, presence of data-tracking content on devices can lead to severe privacy issues, financial losses and even identity theft. To ensure device integrity and user safety, all suspect applications and browser extensions/plug-ins must be removed immediately upon detection.

Default Search, IConverterSearch, AnyRadioSearch and LiveStreamingSearch are some examples of other browser hijackers. They appear legitimate and offer a wide variety of "useful" features. However, these functions rarely work as advertised and in most cases - they do not work at all. In fact, this is true of practically all PUAs. The only goal of unwanted software is to generate revenue for the developers; to users - it has no real value and can instead cause serious problems. PUAs are designed to hijack browsers, cause redirects, run intrusive advertisement campaigns (adware), and collect private data.
How did PDFt Search install on my computer?
PUAs are distributed via download/installation setups of other programs. This deceptive marketing technique of packing ordinary software with unwanted or malicious additions - is called "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipped steps and sections, etc.) - users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to download/install these applications without user permission. Select PUAs have "official" download webpages.
How to avoid installation of potentially unwanted applications?
It is important to research software before download/installation and/or purchase. Only official and verified download channels. Since untrustworthy sources, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content. When downloading/installing, it is recommended to read terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out from additional apps, tools, features, etc. Intrusive adverts appear legitimate and harmless, however they redirect to unreliable and questionable sites (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with such ads and/or redirects, users must inspect their devices and immediately remove all suspicious applications and browser extensions/plug-ins from them. If your computer is already infected with PDFt Search, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
