What Is PUP.DownloadMaster?
PUP.DownloadMaster is a type of potentially unwanted program that can be installed on your computer without your knowledge or consent. It may be bundled with other software or downloaded from the internet, often through deceptive or misleading means. PUPs like PUP.DownloadMaster can cause a range of problems, including slowing down your computer, displaying unwanted advertisements, and potentially exposing your personal data to risk.
How PUP.DownloadMaster Operates
PUPs like PUP.DownloadMaster typically operate by installing themselves on your computer and then running in the background, often without your knowledge or consent. They may collect data about your browsing habits, search history, and other online activities, which can be used to display targeted advertisements or sold to third-party companies. In some cases, PUPs can also download and install additional malware or unwanted software on your computer, further compromising your security.
Symptoms of Infection
If your computer is infected with PUP.DownloadMaster, you may notice a range of symptoms, including slowed performance, unwanted advertisements or pop-ups, and changes to your browser settings or homepage. You may also notice that your computer is running more slowly than usual, or that your internet connection is being used for unknown purposes. In some cases, you may not notice any symptoms at all, which is why it's essential to run regular virus scans and monitor your computer's behavior closely.
How to Remove PUP.DownloadMaster
- Boot your computer in Safe Mode with Networking to prevent PUP.DownloadMaster from running and interfering with the removal process.
- Use a reputable anti-malware tool, such as SpyHunter, to perform a full scan of your computer and detect any malware or unwanted software that may be present.
- Uninstall any suspicious programs or software that you don't recognize or no longer need, as these may be related to the PUP.DownloadMaster infection.
- Reset your web browsers, including Chrome, Firefox, and Edge, to their default settings to remove any changes made by the PUP.
- Reboot your computer and run another scan with your anti-malware tool to ensure that the PUP.DownloadMaster has been completely removed.

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 |

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.FDD
