How to remove the Pro Search browser hijacker

What is Pro Search?

Browser hijacking apps promote fake search engines. In this case, Pro Search promotes tailsearch.com. Furthermore, these rogue apps also track and record data. Commonly, users download and install browser hijackers inadvertently and, therefore, Pro Search is categorized as a potentially unwanted application (PUA).

After installation, browser hijackers changes settings such as the address of the default search engine, homepage, and new tab to the address of a fake search engine. I.e., they ensure that users are forced to visit these sites when they enter search queries into the URL bar, or open a browser/new tab.

Pro Search does not actually change the aforementioned settings, however, it detects when users enter search queries into the URL bar and then redirects them to tailsearch.com. Depending on users' geolocations, tailsearch.com redirects to google.com or bing.com and provides results generated by Google or Bing.

I.e., it does not generate unique results and this is the main reason why it is classified as a fake search engine. Note that, before opening the bing.com web page, tailsearch.com redirects users through my-search.com and search-checker.com, and various other dubious addresses.

In most cases, users can only remove addresses of a fake search engines from browser settings when the browser hijackers that promote them are no longer installed. Pro Search and other apps of this type are also designed to collect various data. They usually target details such as IP addresses, geolocations, entered search queries, addresses of visited pages, etc.

In some cases, they gather confidential, sensitive information as well. The details could be sold to third parties (potentially, cyber criminals) or misused to generate revenue in other ways. Therefore, browser hijacker can lead to problems relating to browsing safety, privacy, and even identity theft.

Some examples of other browser hijackers that function like Pro Search are DirectStreamSearch, Stop Notifications and ConverterSearchPlus.

They are advertised as useful apps that have various features, improve the browsing experience, etc. In fact, most are useless and can cause serious issues. As mentioned, users often download browser hijackers (and other PUAs) inadvertently.

How did Pro Search install on my computer?

Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software. This distribution method is known as "bundling".

Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default.

In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.

When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others).

If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately. If your computer is already infected with Pro Search, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
