What is search.yahoo.com?
Search.yahoo.com is a legitimate search engine, developed by the Yahoo! web services provider. However, users can experience undesirable redirects to it - due to rogue software, called browser hijackers, having infiltrated the browser and/or system.
What are browser hijackers?
Google Chrome, Mozilla Firefox, Internet Explorer and other popular browsers with large user bases are common targets of browser hijackers. Following successful infiltration, they reassign browsers' homepage, default search engine and new tab/window URLs - to the addresses of fake search engines.
Hence, with such software installed, every new browser tab/window opened and every single search query typed into the URL bar - redirect to the address of an illegitimate search engine. Typically, these fake web searching tools cannot provide search results, so they redirect to (or cause redirection chains ending with) Yahoo, Google, Bing or other legitimate search engines.
In some cases this is done by the web search provider's affiliates, as this promotion is monetized. In others - simply to create the impression that the software (i.e. browser hijacker) is a genuine and useful product.
Browser hijackers have no real value to users, as search.yahoo.com (and other legitimate search engines) can be used without involvement of additional software. Furthermore, browser hijackers can install "helper objects", which prevent users from accessing their browser's settings.
Alternatively, the "helper objects" can automatically reset any permitted changes made. Therefore, the browser hijacker must be removed to recover the affected browser.
More details about browser hijackers
What is more, most browser hijackers can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect users' personal information (IP addresses, geolocations and other details). The gathered data is highly likely to contain sensitive and personally identifiable information.
Browser hijacker developers often misuse such data and share it with third parties, intent on doing the same. To summarize, presence of data tracking software on browsers/systems can lead to financial loss, severe privacy issues and even identity theft.
To ensure device integrity and user safety, all suspicious applications and browser extensions/plug-ins must be removed immediately upon detection.

Browser hijackers in general
There are countless browser hijackers available on the Web. They are promoted as legitimate and useful software. Browser hijackers usually offer a wide variety of "handy" features.
The advertised functions can range from easy access to weather, maps, package tracking, film/TV streaming services and other content to providing fast searches and accurate search results. However, these features rarely work as promised and in most cases - they do not work at all.
Browser hijackers that promote search.yahoo.com are Protect My Search App, Unit Conversion Tab, Coupon Search, Templates Here Tab, Online Forms Hub, Weather Waves and many others. While, search.yahoo.com is a genuine search engine with no relation to viruses or malware, the software causing redirects to it - can be responsible for various issues.
How did search.yahoo.com install on my computer?
Browser hijackers and other PUAs can infiltrate systems in several ways. They can be downloaded from "official" promotional websites.
However, they also proliferate through download/installation setups of other programs. The deceptive marketing method of packing ordinary software with unwanted or malicious additions is called "bundling".
This technique is frequently used by freeware developers to generate revenue from their "free" products or by designers of untrustworthy content to promote it by abusing the popularity of legitimate programs. It is often possible to opt-out from these additions, however such options are typically hidden behind "Custom/Advanced" download/installation settings.
Therefore, rushed download/installation processes (e.g. ignored terms, skipped steps and sections, used presets, etc.) - increase the risk of unintentionally allowing bundled content into devices. When clicked on, intrusive advertisements can execute scripts, designed to stealthily download/install unwanted software.
How to avoid installation of potentially unwanted applications?
It is highly recommended to always research software to verify its legitimacy, prior to download/installation and/or purchase. Only official and trustworthy download channels should be used.
Sources like: unofficial and free file-hosting (freeware) sites, Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders - are advised against use, as they can offer deceptive and/or bundled content. Download/Installation processes should be treated with care.
Therefore, it is important to read terms, study all available options, use the "Custom/Advanced" settings and decline downloading/installing supplementary apps, tools, features and other additions. Additionally, caution should be exercised when browsing.
Intrusive ads usually appear legitimate and harmless, however upon being clicked - they redirect to various unreliable and questionable websites (e.g. gambling, pornography, adult-dating, etc.).
In case of encounters with adverts/redirects of this kind, it is of utmost importance to inspect the system and immediately remove all suspect applications and/or browser extensions/plug-ins from it. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate it.
