How to remove search.trustenviroment.com browser hijacker from Mac?

What is search.trustenviroment.com ?

Search.trustenviroment.com is the address of a fake search engine, it is called fake because it does not generate its own, unique results. As a rule, fake search engines/their addresses are promoted by potentially unwanted applications (PUAs) that are classified as browser hijackers. Adware can be designed to promote fake search engines too. It is worthwhile to mention that such apps can be and often are designed to collect various information as well. In most cases users download and install them unknowingly, unintentionally. It is known that search.trustenviroment.com is promoted via a unofficial, fake installer for Adobe Flash Player.

Typically, browsers get hijacked when a certain PUA (e.g., browser hijacker or adware) changes their settings such as address of a default search engine, homepage and new tab to an address of some fake search engine. Research shows that in this case search.trustenviroment.com gets assigned as a default search engine. It is called fake because it provides results generated by Yahoo - search.trustenviroment.com redirects users to search.yahoo.com. Typically, users of hijacked browsers can remove address of a fake search engine from browser settings only when a certain PUA that is designed to promote it is no longer installed. As mentioned in the introduction, such unwanted apps can be designed not only to promote fake search engines but also to collect various data. More often than not they gather details like entered search queries, addresses of visited pages, geolocations, IP addresses. However, in some cases they are capable of accessing sensitive information as well. The bigger problem with it is that their developers could sell collected information to third parties (potentially cyber criminals) or misuse it to generate revenue in other ways. As a result users may become victims of identity theft, experience issues related to online privacy, browsing safety, or other problems. If some PUA is installed on a browser and/or computer, then it should be removed as soon as possible.

More examples of fake search engines are search.getstranto.club, search.standartanalog.com and search.navigationbuffer.com. Typically, they are advertised as useful search engines that supposed to provide accurate search results. However, most of them do not provide any unique results - they display results generated by some other, legitimate search engine like Yahoo, Google, Bing. Although, some fake search engines provide their own results that include links to questionable pages. As mentioned above, most of the times fake search engines are promoted by potentially unwanted applications.

How did search.trustenviroment.com install on my computer?

Research shows that search.navigationbuffer.com is promoted through some fake Adobe Flash Player installer. It is not safe to use such installers because they can be designed to install malware, for example, ransomware, some Trojan-type malware. PUAs that change browser settings to promote some fake search engine can also be distributed through download and/or installation setups of other programs by including them in those setups as additional offers. This distribution method is known as "bundling". As a rule, those offers can be found and declined in "Custom", "Advanced" and other similar settings of setups. Nevertheless, not all users check and change those settings (or untick certain available checkboxes). When users leave the aforementioned settings unchanged, they allow for PUAs to be downloaded and/or installed together with the programs that have them included in their setups. Additionally, unwanted software can be downloaded and/or installed by clicking deceptive advertisements that are designed to execute certain scripts. In most cases such ads appear on untrustworthy websites.

How to avoid installation of potentially unwanted applications?

It is recommended to download programs (and files) from official websites and through direct links. It is not safe to use any other sources, tools for that. For example, third party downloaders, unofficial websites, Peer-to-Peer networks like torrent clients, eMule, etc. Third party installers should not be used too. Also, it is advised to analyze download and/or installation setups that contain settings like "Custom", "Advanced" and see if they mention offers to download and/or install unwanted applications. One more way to avoid unwanted downloads and/or installations is not to click ads that are displayed on questionable websites. They tend to be designed to promote untrustworthy pages and can be designed to download, install unwanted software. If there are any suspicious, unwanted extensions, plug-ins and/or add-ons installed on a browser or applications of this kind installed on the operating system, then they should be uninstalled. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
