Security.Hijack is deemed a potentially unwanted program that performs malicious actions once installed on the computer. This detection by the Malwarebytes Anti-Malware program is given to specific software that users may optionally install together with third-party applications. However, due to a lack of notification during the install process, Security.Hijack often gets into the PC without the user’s knowledge. Thus, you may see unwanted programs on the computer without notice.

In general, Security.Hijack was made by hackers to disable or lessen the protection on the infected computer by disabling the anti-virus program and firewall settings. It can accomplish this task through the modification of the Windows registry and the integration of malicious files into the process. Therefore, if you feel that something is weird about the anti-virus program, it is better to run a scan via online or removable drives such as USB.

How does it infect the computer?

In the usual situation, Security.Hijack is bundled with freeware or shareware applications. In fact, there may be other unwanted programs that are packed into the main software that users prefer to obtain. The authors behind malicious programs are utilizing a pay-per-install scheme to deploy their products over the Internet.

There are also instances where malware is being used to deploy Security.Hijack. In this case, the threat can be acquired by visiting malicious web pages, downloading compromised files, or using file-sharing apps. Links from spam emails and social media sites are also one medium consumed by attackers to spread Security.Hijack.

How does this malware operate?

Once Security.Hijack is run on the computer, it targets mostly known browsers like Microsoft Edge, Google Chrome, Mozilla Firefox, and Safari. This threat performs changes to browser settings that may result in home page hijacking and browser redirect problems. Security.Hijack also drops extensions, add-ons, and plug-ins to achieve other malicious tasks.

To start instantly when the browser is opened, Security.Hijack installs itself as a browser helper object. This also gives the malware control over the browser and allows it to install its own search engine and toolbar objects.


When a computer is infected with the Security.Hijack virus, users may experience a variety of symptoms indicating compromised security. A noticeable decrease in system performance may occur, as Security.Hijack often consumes resources and slows down overall operations. Unusual pop-ups from security software and system alerts may also become frequent, indicating potential malware activity.

In addition, unexpected crashes or system instability may arise, as Security.Hijack can interfere with the normal functioning of the operating system. Additionally, changes to the desktop background, appearance of unfamiliar icons, or alterations to system settings may be signs of a security breach. Another common symptom is the sudden appearance of new and unknown programs on the computer, potentially installed by the virus without the user’s consent. Lastly, compromised security may lead to unauthorized access or theft of personal information, resulting in identity theft, unauthorized transactions, or other forms of cybercrime.
