ProStreamsSearch browser hijacker removal instructions
What is ProStreamsSearch?
ProStreamsSearch is a piece of dubious software, designed to modify browser settings in order to promote prostreamssearch.com - an illegitimate search engine. Due to this, ProStreamsSearch is classified as a browser hijacker. Additionally, software within this classification typically collects browsing-related information. Since most users download/install browser hijackers inadvertently, they are also deemed to be PUAs (Potentially Unwanted Applications).
Browser hijackers assign the addresses of illegitimate web searchers (e.g. prostreamssearch.com) as browsers' homepage, default search engine and new tab/window URLs. These seemingly minor changes seriously affect browsing. To elaborate, with ProStreamsSearch installed: new browser tabs/windows opened and web searches done via the URL bar - redirect to prostreamssearch.com. Furthermore, fake search engines are rarely able to provide search results, so they tend to redirect to (or cause redirection chains ending with) Google, Bing, Yahoo and other legitimate ones. This is the case with prostreamssearch.com, it redirects to the Yahoo (search.yahoo.com) search engine. Browser hijackers can restrict/deny access to the browsers' settings and/or undo any permitted changes made. Hence, recovering a hijacked browser is impossible without eliminating the software affecting it. As mentioned in the introduction, most browser hijackers have data tracking abilities and it is highly likely that ProStreamsSearch has them as well. This software typically monitors browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect sensitive information extracted from it (IP addresses, geolocations and other details). The collected data usually contains personally identifiable information. What is more, this information is then monetized by being shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of data-tracking software on devices can lead to severe privacy issues, financial losses and even identity theft. To protect device integrity and user safety, all suspicious applications and browser extensions/plug-ins removed immediately upon detection.

Dosearch Lite, StreamSearchFinder, GoIncognitoSearch and ClickMovieSearch are some examples of other browser hijackers. They appear legitimate and offer various "handy" functionalities. However, these functions seldom work as advertised and in most cases - they do not work at all. In fact, this applies to nearly all PUAs. The sole purpose of unwanted software is to generate revenue for the developers; therefore, functionality and user safety are irrelevant. PUAs are designed to modify browsers, force-open untrustworthy and malicious websites, deliver intrusive advertisement campaigns (adware), and collect vulnerable data.
How did ProStreamsSearch install on my computer?
PUAs are distributed through download/installation setups of other programs. This deceptive marketing tactic of packing regular software with unwanted or malicious additions - is termed "bundling". Rushed downloads/installations (e.g. ignored terms, skipped steps, used pre-set options, etc.) increase the risk of unintentionally allowing bundled content into the system. Intrusive ads proliferate PUAs as well. Upon being clicked, the advertisements can execute scripts to stealthily download/install these applications. PUAs may also have "official" promotional sites, from which they can be downloaded.
How to avoid installation of potentially unwanted applications?
It is advised to research software products prior to download/installation and/or purchase. Only official and verified download channels must be used. Unofficial and free file-hosting (freeware) websites, P2P sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders and other third party downloaders - are considered to be untrustworthy, as they commonly offer harmful and/or bundled content. Download and installation processes must be approached with caution; that entails - reading terms, exploring all available options, using the "Custom" or "Advanced" settings and opting-out from supplementary apps, tools, features, and so on. Intrusive adverts appear legitimate, however they redirect to various questionable webpages (e.g. adult-dating, pornography, gambling, and many others). In case of encounters with ads and/or redirects of this kind, the system must be checked and all suspect applications and browser extensions/plug-ins detected - removed immediately upon detection. If your computer is already infected with ProStreamsSearch, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
