Typically, the homepage, new tab URL and a customized search engine are applied to the Google Chrome, Mozilla Firefox, Safari, Internet Explorer, or another browser, as soon as a potentially unwanted program is installed on users' machines. Because PUPs spread in many deceptive ways, users may not immediately notice when the Kshowonline hijack occurs.

Provided by a well-known marketing company ChumSearch, the search engine immediately takes over users' web browsing by showing them sponsored links at the top of search results. Both sponsored and organic search results are presented in the same virtual way, so there is almost no way to distinguish which link is an ad. As a result, infected users may start visiting affiliated sites without knowing it. Besides, is also designed to record various information about users and their devices for maximum monetary ad revenue.

Even though is not a dangerous virus, keep in mind that you will not be able to reset your browser to the primary state as long as a potentially unwanted program is installed on your system. There can be multiple browser extensions (such as Kshowonline_DS), as well as standalone applications that could initiate the changes within your browser. Therefore, removal may vary depending on what is installed on your device.

Even though some users might not see the difference, Kshowonline_DS Search collects personally identifiable information that you provide voluntarily. Be aware that such data includes your credentials, email address, name, surname, etc. As it is provided within a statement of the Privacy Policy of the site:[2]

If you communicate with Us via our support section or via email, we may also collect your email address, name and any information voluntarily submitted by you in connection with such support (for example, your name, company name, and particular support query or request).

Likewise, there is a high possibility that any failures to protect such information might lead you to it being used for targeted scam campaigns or phishing attacks by cybercriminals. As a result, you may lose money or even suffer from identity fraud, which can lead to serious losses and privacy issues. Such a scenario, while unlikely, is not impossible – you should definitely limit the number of companies you share your private data with, and developers should not be one of those. is a browser hijacker which spreads as kshowonline_DS extension on Chrome Web Store.

Additionally, it is vital to know that after hijack, the delivered search results are altered. In other terms, this potentially unwanted program promotes affiliate websites instead of producing query results that are relative to you. Accordingly, they increase their profits from the pay-per-click[3] revenue they receive.

Another annoying feature of this browser hijacker is Kshowonline redirect. You can not only continuously see MacKeeper's pop-up ads but also receive other intrusive advertisements in the form of banners or in-texts. Such actions are much more dangerous than it might seem.

If clicked, scam pages may appear right in front of your eyes without warning. Online fraud is prevalent on computers that have potentially unwanted programs installed, as the developers do not properly check the advertising networks they associate with. As a result, adware and browser hijackers may expose users to sites that claim outdated software or viruses are present on your machine. This may lead to the installation of other PUPs or even malware.

Therefore, we highly suggest you remove Kshowonline from your computer and the web browsers. In some cases, manual elimination can be extremely simplistic. For example, you may just need to get rid of a suspicious extension on your web browser or reset it as per the instructions below.

Nevertheless, it sometimes may be difficult to determine which program is causing redirects in the first place. In such a case, a scan with anti-malware software that includes PUP scanning feature can be highly efficient – it would be able to get rid of unwanted apps automatically. Note that, if you had malicious software installed on your system, it might start lagging or crashing after its termination. Thus, we highly advise you scan your machine with Reimage Reimage Cleaner Intego or a similar repair tool.

Do not skip steps during the installation of freeware to avoid PUPs 

There are two ways how your computer can get infected with this browser hijacker — you can either download it directly from Chrome Web Store, or it might sneak into your system together with free software. The latter distribution method, while legitimate, may sometimes be largely unfair.

Developers put browser hijackers inside the installers of freeware as pre-selected additional components. Likewise, Quick/Recommended parameters skip multiple steps, and users are not allowed to de-select them. Therefore, you should never agree to install third-party software with the previously mentioned settings.
