1, home page and new tab abnormal changes
the familiar homepage that was originally set, such as the commonly used search engine or information website, was suddenly replaced by an unfamiliar page, and even every time you open the browser, you will jump to an unknown site containing a large number of advertisements; the new tab page is no longer the default blank page or the commonly used shortcut page, replaced by an interface full of promotional information, and manually modified settings were quickly changed back, which is one of the most common manifestations of browser hijacking.
2, search results were maliciously tampered with
use the browser's built-in search or common search engines, the first few search results are not relevant formal content, but a large number of advertising links, false promotion information that have nothing to do with the query keywords, and even forced to jump to malicious websites. Even if the search engine is changed, this tampering still exists, indicating that the browser has been hijacked.
3, pop-up ads and automatic downloads
browse a web, frequently pop up a variety of can not be closed or closed immediately after the advertisement pop-up window, the content is mostly false financial management, poor product promotion; sometimes in the case of no operation, automatically download unfamiliar installation packages or plug-ins, these are typical signs of browser hijacking.

At the same time, check the list of extensions or plug-ins to see if there are unfamiliar plug-ins that have not been installed by themselves. Such plug-ins are often the carrier of browser hijacking.
2 View system start-up items and process
open the task manager of the system to see the running process, whether there are unfamiliar and unknown processes that occupy a lot of resources; then check the startup item through the system settings to confirm whether there are unfamiliar programs that have not been added by themselves with the system start-up. These unfamiliar processes and startup items may be malicious programs that trigger browser hijacking, which need to be investigated.
in addition to manual self-examination, with the help of professional tools can more accurately and comprehensively detect browser hijacking, especially for hidden malicious programs.
