Quick Search Tool browser hijacker removal instructions
What is the Quick Search Tool browser hijacker?
Quick Search Tool is a rogue application, categorized as a browser hijacker. It operates by making changes to browsers in order to promote quicksearchtool.com - a fake search engine. This browser hijacker also has data tracking abilities, which are employed to spy on users' browsing habits. Furthermore, due to the questionable methods used to distribute Quick Search Tool, it is deemed to be a PUA (Potentially Unwanted Applications).
Browser hijackers primarily target Google Chrome, Mozilla Firefox, Internet Explorer and other popular browsers with large user bases. Following successful installation, these dubious apps reassign browsers' homepage, default search engine and new tab/window URLs - to the addresses of fake web searchers. Hence, with such a piece of software installed: new browser tabs/windows opened and every single web search done via the URL bar - redirect to the promoted address. Quick Search Tool promotes quicksearchtool.com in this manner as well. Illegitimate search engines are rarely capable of providing search results, so they redirect to (or cause redirection chains ending with) legitimate ones. The web searcher of Quick Search Tool (quicksearchtool.com) is not an exception to this, it redirects to Yahoo (search.yahoo.com) - a genuine search engine. Browser hijackers can restrict/deny access to the browser's settings and/or undo any permitted changes made. Therefore, without removing the browser hijacker - it is impossible to recover the affected browser. What is more, Quick Search Tool can track data, which is a common ability of browser hijackers. It can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather vulnerable information extracted from it (IP addresses, geolocations and other details). The collected data often contains personally identifiable information and browser hijacker developers typically monetize this data by sharing it with and/or selling it to third parties (potentially, cyber criminals). In summary, presence of data-tracking software on browsers/systems can lead to system infections, financial losses, severe privacy issues and even identity theft. To ensure device integrity and user safety, it is crucial to eliminate all suspicious applications and browser extensions/plug-ins immediately upon detection.

Flare Search, DPS Websafe, Remove Notifications, StreaminSearchs - are some examples of other browser hijackers. They seldom appear suspect, this software usually looks legitimate and useful. Users are enticed into download/installation with offers of a wide variety of functionalities. However, in most cases, the advertised features are nonoperational. In fact, this applies to practically all PUAs. The only purpose of unwanted applications is to generate revenue for the developers. Therefore, instead of delivering on any promises, PUAs modify browsers, cause redirects, run intrusive advertisement campaigns and collect private data.
How did Quick Search Tool install on my computer?
Select PUAs (e.g. Quick Search Tool) have "official" download sites. These apps can also be downloaded/installed together with other products. "Bundling" is the term used to define this false marketing technique of pre-packing regular software with unwanted or malicious additions. By rushing through download/installation processes (e.g. by ignoring terms, skipping steps and sections, etc.) - users risk unintentionally allowing bundled content into the system. Intrusive ads proliferate PUAs as well; once clicked on, they can execute scripts to make stealthy downloads/installations.
How to avoid installation of potentially unwanted applications?
It is advised to research software prior to download/installation and/or purchase. All downloads must be done official and verified sources. Untrustworthy channels, like: unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders - often offer bundled content. When downloading/installing, it is important to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features and other additions. Intrusive advertisements appear ordinary, however they redirect to various questionable webpages (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with such adverts/redirects, users must inspect the system and immediately remove all dubious applications and/or browser extensions/plug-ins from it. If your computer is already infected with Quick Search Tool, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
