What is pdfsrch.com?
pdfsrch.com is the address of a fake search engine. These bogus search tools are typically unable to provide unique results. They are promoted by Potentially Unwanted Applications (PUAs) classified as browser hijackers.
Note that pdfsrch.com has been observed being promoted by the DoctoPDF, PDF Opener, MyDocsToPDF, ViewPDF, EasyConvert and Easy Conversion browser hijackers. This rogue software makes modifications to browser settings and restricts/denies access to them.
Additionally, most browser hijackers have data tracking capabilities, which are employed to monitor users' browsing activity.
Browser hijackers may seem legitimate and offer various "useful" functionalities, however, the advertised features are rarely operational. They target Google Chrome, Mozilla Firefox, Internet Explorer and other popular browsers with large user bases.
Following successful infiltration, browser hijackers reassign the homepage, default search engine and new tab/widow URLs to the addresses of fake search engines. To elaborate, with a browser hijacker promoting pdfsrch.com installed, each new browser tab/window opened and each search made via the URL bar, redirects to pdfsrch.com.
As mentioned, bogus search engines are seldom capable of providing useful results, and so they tend to redirect to (or cause redirection chains ending with) Yahoo, Google, Bing and other genuine search engines. This is the case with pdfsrch.com, which redirects to Yahoo (search.yahoo.com) or Bing (bing.com).
Furthermore, recovering a hijacked browser is impossible without removing the software affecting it, since any changes users attempt to make to are automatically reset (if access is permitted at all). Most browser hijackers can track data.
They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect sensitive information extracted from it (IP addresses, geolocations and other details). This data is likely to contain personally identifiable information.
Furthermore, browser hijacker developers often monetize this information by sharing it with and/or selling it to third parties (potentially, cyber criminals). To summarize, the presence of data-tracking software can lead to financial loss, serious privacy issues and even identity theft.
To ensure device integrity and user safety, you are strongly advised to eliminate all suspect applications and browser extensions/plug-ins immediately upon detection.

mybrowser-search.com, searchred01.xyz, prudensearch.com and pdfmagicsearch.com are some examples of other bogus search engines. On initial inspection, they may seem genuine and useful, and they often claim that they can provide accurate search results, improve web search privacy and safety, etc, however, they typically cannot generate any search results at all.
In the rare cases when they can, the results tend to be inaccurate and/or promote untrusted/malicious websites.
How did pdfsrch.com install on my computer?
Some PUAs have "official" promotional web pages, from which they can be downloaded, however, they are more commonly downloaded/installed with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".
Rushing download/installation processes (e.g. ignoring terms, skipping steps, using pre-set options, etc.) increases the risk of inadvertent installation of dubious and/or bundled content. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.
How to avoid installation of potentially unwanted applications
You are advised to research all products prior to download/installation. Use only official and verified download channels. Untrusted download sources such as unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders can offer deceptive and bundled content.
Therefore, they should be avoided. Treat download and installation processes with caution - read the terms, study all available options, use the "Custom" or "Advanced" settings, and opt-out of additional apps, tools, features, and so on. It is also important to exercise caution when browsing.
Intrusive ads usually seem normal, however, they often redirect to dubious sites (e.g. gambling, pornography, adult-dating, etc.).
If you encounter these ads/redirects, check the system and remove all suspicious applications and browsing extensions/plug-ins without delay. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate it.
