PUP.Gamehack.DJA is a detection name used to flag a potentially unwanted program (PUP) that has been observed bundled with or disguised as legitimate Windows software installers. While it is not classified as highly dangerous, its presence on a system is still considered unwanted because it can be installed without a user's full knowledge or clear consent, and it may bring along extra behaviors that affect the user experience.

What PUP.Gamehack.DJA Does
Like most programs in the Possibly Unwanted Program category, PUP.Gamehack.DJA is typically bundled alongside other software packages, often riding along with installers for utilities or other downloadable programs. Once present on a system, PUPs of this type commonly exhibit behavior such as installing unwanted browser toolbars, displaying intrusive advertising, or modifying browser settings like the default search engine or homepage without clear user authorization. Analysis of this detection shows it making use of process creation functions and techniques associated with process manipulation, which are typical for installer-type packages that unpack and execute additional components during setup. It has also been observed referencing keyboard state and user object information, functionality that can be found in legitimate software but may also indicate broader monitoring capabilities in bundled or repackaged installers.
How It Usually Gets Onto Computers
PUPs such as this one are generally not deliberately sought out by users. Instead, they typically spread through software bundling, where a user intends to install one specific program but inadvertently agrees to install additional, unrelated software during the setup process. This often happens when users click through installation wizards quickly, skipping over custom or advanced installation options that would have allowed them to deselect bundled extras. Downloads from third-party download portals, free software aggregator sites, and peer-to-peer file sharing networks are common sources for these types of bundled installers.
Risks for the User
With a danger level rated low, PUP.Gamehack.DJA is not considered a severe threat in the way that ransomware or data-stealing malware would be. However, its presence can still create risks and annoyances. These typically include unwanted changes to browser configurations, an increase in intrusive advertising, degraded system or browser performance, and the installation of additional unwanted components without full user awareness. In some cases, PUPs can also make it more difficult to fully remove unwanted software, as components may be designed to persist or reinstall themselves.
Signs of Infection
Users affected by this type of PUP may notice new toolbars or browser extensions they do not recall installing, unexpected changes to their browser's homepage or default search engine, an increase in pop-up ads or sponsored content, and new programs appearing in their installed applications list that they do not remember adding. Slower system or browser performance can also be a sign that unwanted software is running in the background.
How to Stay Protected
To reduce the risk of encountering PUPs like this one, users should download software only from official vendor websites or trusted sources, rather than third-party download portals. During installation, it is important to choose custom or advanced setup options whenever available, carefully reviewing each step and deselecting any bundled offers that are not wanted. Keeping an eye on installed programs and browser extensions, and removing anything unfamiliar, can also help maintain a clean and well-controlled system.

Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |
