Table of Contents
What Is PUP.Gamsoft?
PUP.Gamsoft is a type of malware that is classified as a potentially unwanted program. This category of threats includes software that may not be malicious in the classical sense but can still cause significant problems for users. PUPs often sneak onto systems through bundled installations, deceptive downloads, or exploited vulnerabilities. They can lead to a range of issues, from annoying advertisements and unwanted software installations to more severe problems like data theft and system crashes.
How PUP.Gamsoft Operates
PUP.Gamsoft, like other PUPs, operates by integrating itself into your system, often without your knowledge or consent. It may modify system settings, registry entries, and browser configurations to achieve its goals, which could include displaying unwanted advertisements, collecting user data, or installing additional unwanted software. The presence of a PUP can significantly affect your computer's performance, leading to slower operation, increased risk of other infections, and potential privacy violations.
Symptoms of Infection
Identifying a PUP.Gamsoft infection can be challenging, as it may not exhibit overtly malicious behavior immediately. However, common symptoms of PUP infections include an increase in pop-up advertisements, new toolbars or extensions in your browser that you did not install, changes in your browser's homepage or search engine, and overall system slowdown. If you notice any of these symptoms, it is crucial to investigate further and consider taking removal actions.
- Increased advertisements and pop-ups
- New, unwanted browser extensions or toolbars
- Changes to browser settings
- System performance issues
How to Remove PUP.Gamsoft
- Boot your computer in Safe Mode with Networking to prevent the malware from loading and to give you a clean environment to work in.
- Perform a full scan of your system using a reputable anti-malware tool, such as SpyHunter, to detect and remove all components of the PUP.
- Manually uninstall any suspicious programs that you do not recognize or that were installed around the time the symptoms started.
- Reset your browsers (Chrome, Firefox, Edge, etc.) to their default settings to remove any unwanted changes made by the PUP.
- Reboot your computer and perform another scan with your anti-malware tool to ensure that all threats have been removed.
Conclusion
Removing PUP.Gamsoft from your system is crucial to restoring your computer's security and performance. By following the steps outlined above and maintaining good computing practices, such as regularly updating your software, using strong antivirus programs, and being cautious with downloads and email attachments, you can protect your system from future infections. Remember, vigilance and proactive measures are key to a safe and secure computing experience.

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 |
|---|---|---|
| Gamsoft Sistemas de Informação Ltda. | DigiCert Global G3 Code Signing ECC SHA384 2021 CA1 | Self Signed |
| Gamsoft Sistemas de Informação Ltda. | DigiCert Trusted G4 Code Signing RSA4096 SHA384 2021 CA1 | Self Signed |

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- Agent.SGA

Registry Modifications
Registry Modifications
This section lists registry keys and values that were created, modified and/or deleted by samples in this family. Windows Registry activity can provide valuable insight into malware functionality. Additionally, malware often creates registry values to allow itself to automatically start and indefinitely persist after an initial infection has compromised the system.| Key::Value | Data | API Name |
