Many "browser home page hijacking" are done through malware or plug-ins.

"I checked a lot of solutions on the Internet, such as changing browser settings, deleting the registry, and so on. Even if some software is uninstalled, the browser home page will still be changed after the computer is restarted."you can't fix it with any security tool, killing virus or emptying the DNS cache won't help." ……

The way to detect this kind of hijacking is to enter the domain name in the monitoring of the iis7 website for real-time detection, which can help determine the security risks at the moment, and also detect what the specific security problems are at the moment.

Although some computer professional websites have set up special topics for modifying the browser home page, including Jinshan poison bully also explained how to unlock the drug bully navigation, but for most users, after the browser home page is hijacked, it is often time-consuming and even unable to solve the problem.

According to professionals, from simple to complex, there are generally several ways to "save" the home page. Suitable for ordinary users, including restart the computer, uninstall the software, reset the browser, antivirus and so on. But many users report that these methods are of no use. Relatively need professional knowledge, such as setting the lock of the browser home page in the browser protection function of the security software, finding and modifying the registry of the system, clearing the malicious programs that start automatically at startup, modifying the browser shortcut properties on the desktop, and so on. But for some netizens, it still can't solve the problem.

Who is behind this? A software engineer revealed that, in fact, for computer professionals, the "browser home page hijacking" behind the technical operation threshold is not high.

As far as modifying the home page is concerned, it can be achieved by mixing code into the software, grabbing permissions, exploiting vulnerabilities, and so on. According to experts, in many cases, according to the strategy explored on the Internet, the browser home page can be modified back, but for most ordinary users, the concepts of "task process" and "registry" alone are difficult to understand. Like "uninstalling the driver wizard needs to kill the process in the task manager first, smashing the folder can strongly delete the sub-files if it fails", it is even more difficult to understand.

But many times, these methods of changing back to the home page do not work, even if you restore the original settings, they will be changed back. Liu Qixu, an associate researcher at the Information Engineering Research Institute, said that this is a way to cure the symptoms rather than the root causes. A lot of "browser home page hijacking" is done through malware or plug-ins, and the home page will be changed back if it is not cleared. Some software will monitor the current browser settings in the background and re-hijack the home page once they find that the settings have been reset. Another way is to hijack the home page through the user's home router, which can be done without modifying the user's computer settings, which is very hidden and difficult to eliminate.

"it's not the most frightening thing to make users aware of changes to the browser's home page." 'The most frightening thing is the Internet technology bullying that users are not even aware of, 'said one software engineer. He said, for example, that Mining *, a virus program that implants and earns bitcoin on a user's computer, used a low-level version in 2017, and when the user's computer was infected, they could feel that the computer was running slower. But in 2018, after the upgrade of "Mining *", it became not running during the day, and users did not start running until they closed their computers at night. "users are not aware of it, but in fact they have been stolen traffic and resources, and have been 'bullied' all the time. On the Internet, users are often the weak side in the face of complex technologies.
