Written by Tomas Meskauskas on (updated)
What kind of extension is Guardian Angel?
We have inspected the Guardian Angel application and found that it has capabilities commonly associated with browser hijackers. During our examination, we noticed that Guardian Angel is designed to promote boyu.com.tr. It is advisable to avoid using apps like Guardian Angel and visiting sites like boyu.com.tr.
Guardian Angel overview
A typical browser hijacker changes the settings of a web browser to promote a fake search engine or other unreliable page. However, Guardian Angel carries out its activities without changing any settings. This app detects when a search query is entered and redirects users to boyu.com.tr.
Since boyu.com.tr is associated with Guardian Angel (and other apps intended to hijack browsers), it should not be trusted. Such associations suggest that the search engine might engage in unethical practices, including unauthorized data collection, redirecting users to potentially harmful websites, and displaying misleading search results.
Boyu.com.tr may gather information about the websites visited by users, details of the searches conducted on the search engine, details about the user's device, information about the user's geographical location, and even sensitive details. This data may be used for various purposes, including malicious ones.
Moreover, boyu.com.tr may present misleading results directing users to phishing websites, pages hosting potentially malicious apps, fake giveaways, lotteries, adult sites, and similar web pages. Therefore, it is strongly advisable to avoid using boyu.com.tr and use reputable search engines like Google instead.

Apps of this type in general
Typically, browser hijackers are promoted as useful tools. For instance, Guardian Angel is promoted as a web security tool that helps users prevent visiting suspicious websites. However, once added to browsers, they change their settings to promote shady addresses (or they promote them without making changes in the settings).
There are numerous examples of browser hijackers (some of them are SearchThisAll, Quest-Finder, and SerachMates.
How did unwanted software install on my computer?
Quite often, users add/install browser hijackers via downloads from unofficial app stores or websites, P2P networks, third-party downloaders, sites hosting pirated/illegal content, etc. It can also be caused via misleading pop-ups, notifications from shady sites, deceptive ads, fake download buttons, and similar channels.
Another popular distribution method is known as bundling. Untrustworthy and (or) free programs are often bundled with browser hijackers or other shady apps. Users agree to install/add unwanted apps by finishing installations without deselecting those apps.
How to avoid installation of unwanted applications?
Use official websites and app stores as sources for downloading software (and files). Avoid downloading from P2P networks, third-party downloaders, and other unofficial channels. Also, do not permit questionable pages to send notifications or interact with ads (and pop-ups, warnings, banners, etc.) on shady web pages.
When installing programs, look for optional apps and deselect them using the provided settings or checkboxes. Avoid opening files and links in suspicious emails or messages. Additionally, regularly update all software and the operating system and use reputable security software.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
