PDFPros browser hijacker removal instructions

What is PDFPros?

PDFPros is yet another deceptive application that claims to allow conversion of various documents to PDF format. Its appearance suggests that PDFPros is a legitimate program, however, it is categorized as a potentially unwanted application (PUA) and a browser hijacker.

There are three main reasons for these negative associations: 1) installation without users' consent; 2) tracking of browsing activity, and; 3) promotion of a fake search engine [feed.pdfpros.com].

As mentioned above, PDFPros promotes the feed.pdfpros.com fake search engine. To achieve this, PDFPros hijacks various popular browsers (e.g., Mozilla Firefox, Google Chrome, Internet Explorer) and modifies the new tab URL, homepage, and default search engine options by assigning them to feed.pdfpros.com.

These changes may seem insignificant, however, users are unable to revert them, since PDFPros reassigns settings to feed.pdfpros.com (or simply prevents access) when attempts are made to change these options. Therefore, returning browsers to their previous states becomes impossible.

Ultimately, users are encouraged to visit feed.pdfpros.com when they open a new browser tab/window or enter a search query into the URL bar. This significantly diminishes the browsing experience. Note that feed.pdfpros.com is a useless search engine, since it generates no unique results and simply redirects users to search.yahoo.com when a search query is entered.

Users merely end up searching via the Yahoo search engine (which is legitimate) and, thus, feed.pdfpros.com is redundant. Another important issue is information tracking. Browser hijacking applications and fake search engines record information such as IP addresses, website URLs visited, pages viewed, search queries, and other information relating to browsing activity.

Collected data usually includes personal details that developers share with third parties (potentially, cyber criminals) who misuse it to generate revenue. Therefore, data tracking can lead to serious privacy issues or even identity theft. We strongly recommend that you eliminate the PDFPros browser hijacker and never visit the feed.pdfpros.com site again.

The internet is full of browser-hijacking applications that share many similarities with PDFPros including Universal Converter, Track Your Transit Info, and EasyWay - the list goes on. By offering many "useful features", these apps attempt to give the impression of legitimacy.

Following infiltration, however, they provide no real value for regular users, since they have just one purpose: to generate revenue for the developers. Browser hijackers cause redirects and gather information. In doing so, these apps diminish the browsing experience and pose a threat to your privacy.

How did PDFPros install on my computer?

PDFPros is free for anyone to download on its official website, however, it infiltrates computers without users’ permission, since browser hijackers are often distributed using "bundling" and intrusive advertising methods. "Bundling" is essentially stealth installation of third party applications together with regular software.

Developers hide "bundled" apps behind "Custom/Advanced" settings (or other sections) of the download/installation processes.

They do not adequately disclose such information. Intrusive advertisements, which are often delivered adware-type applications installed on the system, redirect users to dubious websites or merely run scripts that stealthily download/install unwanted applications.

Users are likely to rush download/installation processes and skip steps. Additionally, they often click various advertisements. This exposes systems to the risk of various infections and compromises users' privacy. Lack of knowledge of these threats and careless behavior are the main reasons for computer infections.

How to avoid installation of potentially unwanted applications?

To prevent PUA infiltration, be very cautious when browsing the internet and downloading/installing software. Carefully analyze each window of the download/installation dialogs using the "Custom" or "Advanced" settings. Decline offers to download/install additional applications and opt-out of those already included.

Download your programs from official sources only, preferably using direct download links. Third party downloaders/installers should never be used, since they often include rogue apps (developers monetize them using the "bundling" method).

Additionally, bear in mind that criminals invest many resources into intrusive ads design, thereby making them seem legitimate. Once clicked, however, they redirect to dubious websites (gambling, pornography, adult dating, and similar). If you experience these ads, eliminate all suspicious applications and browser plug-ins.

If your computer is already infected with PDFPros, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
