How to remove the 4KSportSearchs unwanted application

What is 4KSportSearchs?

4KSportSearchs is a browser hijacker that promotes 4ksportsearchs.com, the address of a fake search engine. Generally, apps of this type hijack browsers by changing their settings.

Furthermore, browser hijackers often collect details relating to users' browsing habits. People mostly download/install apps such as 4KSportSearchs inadvertently and, therefore, they are classified as potentially unwanted applications (PUAs).

Typically, browser hijackers modify settings such as the address of the default search engine, new tab, and homepage, so that users are forced to visit a specific address when they enter search queries into the URL bar, open a new tab or browser window. 4KSportSearchs promotes 4ksportsearchs.com in this way.

4ksportsearchs.com is a fake search engine that redirects users to search.yahoo.com or searchlee.com, depending on the geolocations of its visitors. I.e., the fake search engine that 4KSportSearchs promotes shows results generated by Yahoo or another dubious search engine, which may show links to untrusted pages in its results.

Therefore, do not use 4ksportsearchs.com to search. To remove this address from the settings of a browser that is hijacked by 4KSportSearchs, it is necessary to uninstall the browser hijacker. Typically, browser hijackers do not allow users to make changes to the settings whilst they are installed.

It is likely that 4KSportSearchs also collects information relating to users' browsing activities. For example, geolocations, entered search queries, addresses of visited pages, and Internet Protocol addresses. Furthermore, this app may be capable of accessing personal information such as saved passwords, and credit card details.

Therefore, remove these apps from browsers/computers, otherwise, the collected information could be misused for marketing purposes or monetized in other ways (e.g., sold to third parties - potentially, cyber criminals).

All browser hijackers are similar: they change browser settings and can collect information relating to users. More examples of apps similar to 4KSportSearchs are Games Search, Quick Recipes, and HDSportsSearch.

Typically, apps of this type are available for download on dubious websites, however, most users download and install them inadvertently (see below).

How did 4KSportSearchs 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 download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.

Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations.

Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from the operating system.

If your computer is already infected with 4KSportSearchs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
