Document Converter browser hijacker removal instructions

What is Document Converter?

Document Converter is a deceptive application that supposedly allows users convert the format of various documents. Its appearance suggests that this application is completely appropriate and handy. In reality, however, Document Converter is categorized as a potentially unwanted application (PUA), as well as a browser hijacker. There are three main reasons for these negative associations: 1) stealth installation without user's consent; 2) promotion of a fake web search engine, and; 3) tracking of user's web browsing activity.

search.hdocumentconverter.app browser hijacker

Document Converter is designed to promote search.hdocumentconverter.app fake search engine. To achieve this, Document Converter hijacks web browsers and assigns new tab URL, default search engine, and homepage options as search.hdocumentconverter.app. Changes like such are minor. What's more important is that users are unable to revert them, because Document Converter prevents users from accessing these options or simply reassigns them whenever attempts to change are made. Ultimately, users have no choice but to visit search.hdocumentconverter.app every time they open a new browsing tab or search the web via URL bar. As a result, web browsing quality significantly decreases. It is worth noting that search.hdocumentconverter.app, as a web search engine, is completely useless, because it does not generate any search results by itself. Instead, search.hdocumentconverter.app redirects users to search.yahoo.com whenever a search query is entered. Users simply end up searching the web via Yahoo (a legitimate search engine) and search.hdocumentconverter.app becomes completely irrelevant. Another significant downside is information tracking. Browser-hijacking applications and fake web search engines usually record IP addresses, website URLs visited, pages viewed, search queries, and other similar information about user's web browsing habits. Collected data typically includes personal details and, if that wasn't enough, developers share it with third parties (potentially, cyber criminals. These persons generate revenue by misusing received information. Hence, information tracking might eventually lead to serious privacy issues or even identity theft. Document Converter browser hijacker should be uninstalled and search.hdocumentconverter.app website shouldn't be visited.

Document Converter's developers have released dozens of browser-hijacking applications, all of which are completely identical. Smart Search, Transit Maps Directions and Get Recipes Now are only few examples from a long list. Every single one offers some sort of "useful feature". Yet all of these claims are mere attempts to create the impression of legitimacy and to trick users into installation. Applications like Document Converter have only one purpose: to generate revenue for the developers. Hence, instead of giving any real value for the user, these browser hijackers cause unwanted redirects and gather various information.

How did Document Converter install on my computer?

This browser hijacker does have an official download website. Nevertheless, it often infiltrates computers without user's consent, because developers proliferate it by using intrusive advertising and "bundling" methods. Intrusive advertisements (most of which are delivered by adware-type apps) are designed to redirect users to unreliable websites, as well as execute scripts to download/install various PUAs. "Bundling", on the other hand, is a stealth installation of third patry applications alongside with the regular software. What developers do is hide "bundled" apps behind "Custom/Advanced" settings (or other sections) of download/installation processes. Now the main issues are users' careless behavior and lack of knowledge. They often recklessly rush download/installation processes and skip most of the steps. Such behavior often leads to inadvertent installations of third party programs.

How to avoid installation of potentially unwanted applications?

First of all, users must realize that the key to computer safety is caution, which is why paying attention when browsing the Internet, as well as downloading/installing software is paramount. It is very important to analyze each window of download/installation dialogs using either "Custom" or "Advanced" settings. While doing so, opt-out all additionally included programs and decline all offers to download/install such. You should download programs only from official sources and, if possible, using direct download links. Third party downloaders/installers are typically monetized using the "bundling" method, which is why such tools shouldn't be used. Keep in mind that intrusive advertisements usually look completely appropriate. Once clicked, however, ads expose themselves by redirecting to unreliable websites (gambling, pornography, adult dating, and similar). In case of such ads/redirects users should remove all suspicious applications and browser plug-ins. If your computer is already infected with Document Converter, we recommend running a scan with Spyhunter for Windows to automatically eliminate this browser hijacker.
