Cactus Search browser hijacker removal instructions
What is Cactus Search?
Cactus Search is a piece of rogue software classified as a browser hijacker. It operates by promoting the cactus-search.com fake search engine - through modification of browser settings. Furthermore, Cactus Search has data tracking abilities, which are employed to spy on users' browsing habits. Since browser hijackers are typically downloaded/installed unintentionally, they are also categorized as PUAs (Potentially Unwanted Applications).
Browser hijackers assign fake web searcher addresses as browsers' homepage, default search engine, and new tab/window URLs. Cactus Search also makes these modifications when promoting cactus-search.com. Hence, with this browser hijacker installed: every single search query typed into the URL bar and new tab/window opened - redirect to the cactus-search.com web searcher. Illegitimate search engines seldom can provide search results, so they tend to redirect or cause redirection chains leading to Google, Bing, Yahoo, and other genuine ones. This applies to cactus-search.com as well; it redirects to the Google (google.com) search engine. Furthermore, browser hijackers can reset any changes users try to make to their browsers. Alternatively, this software restricts or denies access to the browser settings outright. Therefore, recovering an affected browser is impossible without removing the browser hijacker.
Cactus Search can track data. Information of interest includes (but is not limited to): URLs visited, pages viewed, search queries typed, IP (Internet Protocol) addresses, geolocations, and personally identifiable details. The collected data is then monetized by being shared with and/or sold to third-parties (potentially, cyber criminals). In summary, the presence of data-tracking software on devices - can lead to severe privacy issues, financial losses, and even identity theft. To ensure device integrity and user privacy, all suspect applications and browser extensions/plug-ins must be eliminated without delay.

SearchMusicStream, Quick App, and NewTaber are a couple examples of browser hijackers. They appear legitimate and offer a broad range of "useful" functionalities. However, despite how good the advertised features may sound - they are rarely operational. In fact, this applies to nearly all PUAs. The only aim of these apps is to generate profit at user expense. Therefore, instead of delivering on any promises, PUAs can modify browsers, force-open untrustworthy and malicious webpages, run intrusive advertisement campaigns (adware), and gather private information.
How did Cactus Search install on my computer?
Some PUAs (e.g., Cactus Search) have "official" promotional/download sites. These applications can also be downloaded/installed together with other products. This false marketing tactic of packing regular software with unwanted or malicious additions - is termed "bundling". Rushed download/installation processes (e.g., ignored terms, used pre-set options, etc.) increase the risk of unintentionally allowing bundled content into the system. Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to make downloads/installations without user permission.
How to avoid installation of potentially unwanted applications?
It is advised to research software products to verify their legitimacy before download/installation and/or purchase. Additionally, all downloads have to be performed from official and trustworthy sources. Dubious download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks (Torrent clients, eMule, Gnutella, etc.), and other third-party downloaders - often offer harmful and bundled content. When downloading/installing, it is recommended to read terms, explore available options, use the "Custom/Advanced" settings, and opt-out from supplementary apps, tools, features, and so on. It is just as important to exercise caution when browsing. Intrusive advertisements appear legitimate and innocuous; however, they redirect to various unreliable and questionable sites (e.g., gambling, pornography, adult-dating, etc.). In case of encounters with ads and/or redirects of this kind, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with Cactus Search, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
