What is the One search pro browser hijacker?
One search pro is a browser hijacker designed to promote tailsearch.com (a fake search engine). Typically, software within this classification promotes bogus search engines by making modifications to browser settings, however, One search pro operates slightly differently.
The common trait throughout browser hijackers is data tracking. One search pro specifically gathers search queries via tailsearch.com. Due to the dubious methods used to proliferate One search pro, it is classified as a Potentially Unwanted Application (PUA).
Browser hijackers primarily target Google Chrome, Mozilla Firefox, Internet Explorer and other popular browsers with large user bases. The usual operation is assigning the browser homepage, default search engine and new tab/window URLs to the addresses of fake search engines.
Therefore, with this type of software installed, the homepage is changed, and new browser tabs/windows opened and search queries typed into the URL bar redirect to the promoted address, however, One search pro does not alter the homepage or the new tab/window URLs.
When users attempt to search (type a search query), they are redirected to search results provided by the Google search engine with tailsearch.com inserted into the redirection chain. Fake search engines are rarely able to generate unique results, and so they tend to redirect to genuine sites (e.g. Google, Yahoo, Bing, etc.).
Furthermore, some browser hijackers can restrict/deny access to the browser settings and/or undo any permitted changes made. As mentioned, most browser hijackers have data tracking capabilities. One search pro is no exception to this, as it collects search queries through tailsearch.com, which is a serious privacy concern.
One search pro might target other information relating to browsing activity. Data of interest usually includes IP addresses, geolocations, URLs visited, pages viewed, and even personally identifiable information. The gathered data is monetized by browser hijacker developers who share it with and/or sell it to third parties (potentially, cyber criminals).
To summarize, the presence of data-tracking software on browsers/systems can lead to serious privacy issues, financial loss and identity theft. To ensure device integrity and user safety, all suspect applications and browser extensions/plug-ins must be removed without delay.

Package Tracker Guru, MyWeatherFree and Online Radio Finder Tab are some examples of other browser hijackers. They may seem normal and useful, and offer a wide variety of functionality, however, they are seldom operational. In fact, this information is true of most PUAs.
The sole purpose of these unwanted applications is to generate revenue for the developers. Regular users receive no real value and can instead experience serious problems. Rather than delivering any real value, PUAs can hijack browsers, cause redirects, deliver intrusive advertisements (e.g. pop-ups, banners, coupons, etc.) and collect private information.
How did One search pro install on my computer?
Certain PUAs (including One search pro) have "official" download web pages. These apps can also be downloaded/installed with other software. This deceptive marketing technique of packing regular programs with unwanted or malicious additions is called "bundling".
By rushing through download/installation processes (e.g. ignoring terms, skipping steps, using pre-set options, etc.), many users risk unintentionally allowing bundled content into the system. Intrusive advertisements proliferate PUAs as well. Once clicked, they can execute scripts to make stealthy downloads/installations.
How to avoid installation of potentially unwanted applications?
You are advised to research all software before download/installation and/or purchase. Use only official and verified download channels, since untrusted sources such as unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders can offer deceptive and bundled content.
Download and installation processes must be treated with caution. Read the terms, study all available options, use the "Custom" or "Advanced" settings and decline offers to download/install additional apps, tools, features, etc. It is also important to exercise caution when browsing.
Intrusive ads may seem legitimate, however, they can redirect to dubious sites (e.g. gambling, pornography, adult-dating, and so on).
If you encounter ads or redirects of this kind, inspect your devices and immediately eliminate all suspicious applications and browser extensions/plug-ins. If your computer is already infected with One search pro, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
