What is musttrust[.]xyz?
Musttrust.xyz is a fake search engine. Fraudulent web searchers like musttrust[.]xyz are usually promoted by PUAs (Potentially Unwanted Applications) categorized as browser hijackers. The Find browser hijacker has been noted promoting musttrust[.]xyz; what is noteworthy is that this rogue extension uses sophisticated persistence-ensuring tactics to stop users from recovering their browsers.
How do browser hijackers promote musttrust[.]xyz?
Browser hijackers typically operate by assigning fake web searcher addresses (e.g., musttrust[.]xyz) as browsers' homepage, default search engine, and new tab/window URLs. While the Find browser hijacker has not been observed making these changes to browsers, it is possible that it can modify browsers in this manner.
Hijacker software promotes search engines by redirecting to them when a new browser tab/window is opened, and when a web search is performed via the URL bar. The Find browser hijacker has been noted promoting musttrust[.]xyz and the peatea[.]xyz fraudulent web searchers.
Fake search engines usually cannot generate search results, so they redirect to genuine ones. This also applies to musttrust[.]xyz; it redirects to the legitimate Bing search engine (possibly others).
Browser hijackers often use various persistence-ensuring techniques. The Find browser hijacker denies access to the Google Chrome extensions list ("chrome://extensions/") and instead displays a fake one ("chrome-extension://[user's_ID]/extensions.html"). Therefore, users can neither see the Find extension present nor can they remove it. Furthermore, this browser hijacker can use the "Managed by your organization" Chrome browser feature.
What is more, most browser hijackers have data tracking abilities. They record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect sensitive information extracted from it (IP addresses, personally identifiable details, etc.). This data is then shared with and/or sold to third-parties.
To summarize, the presence of such unwanted software on devices can lead to serious privacy issues, financial losses, and identity theft.

Fake search engines and browser hijackers in general
Kwiqsearch.com, nearbyme.io, ctcodeinfo.com - are a couple examples of fake search engines, and GameSearchTech, MySearchConverters, IncognitoSearchWeb - of browser hijackers. They appear legitimate and offer "useful" functionalities, which are seldom operational.
This applies to nearly all PUAs. Unwanted apps are designed to hijack browsers, run intrusive ad campaigns (adware), force-open dubious and malicious sites, and collect private data.
How did musttrust[.]xyz promoting software install on my computer?
PUAs are spread using the "bundling" marketing technique - packing regular software with unwanted/malicious additions. Rushed downloads/installations (e.g., used "Easy/Express" settings, etc.) increase the risk of allowing bundled content into the system.
Intrusive adverts proliferate PUAs as well. Once clicked on, the ads can execute scripts to make stealthy downloads/installations. PUAs may also have "official" download pages.
How to avoid installation of potentially unwanted applications?
It is advised to research software and download it only from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled and harmful content.
When downloading/installing, it is recommended to read terms, explore possible options, use the "Custom/Advanced", and opt-out from all additions. Intrusive adverts appear ordinary, yet they redirect to highly questionable websites (e.g., gambling, adult-dating, pornography, 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 browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate it.
