What Is PUP.Downer.B?
PUP.Downer.B 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 nature but can still cause problems for computer users. PUPs can be installed on a system without the user's knowledge or consent, often through bundled software downloads or deceptive installation practices. They can consume system resources, display unwanted advertisements, and collect user data without permission.
How PUP.Downer.B Operates
PUP.Downer.B, like other PUPs, can operate in various ways to achieve its goals. It may install itself as a browser extension or add-on, allowing it to monitor and control browsing activities. It could also run as a background process, consuming system resources and potentially slowing down the computer. The primary objective of PUP.Downer.B is likely to generate revenue for its creators through advertisements, data collection, or by selling user information to third parties.
Symptoms of Infection
Identifying a PUP.Downer.B infection can be challenging, as it may not exhibit overtly malicious behavior. However, some common symptoms include unexpected advertisements or pop-ups, changes in browser settings, slow system performance, and unfamiliar programs or icons on the desktop or start menu. Users may also notice that their browser homepage or search engine has been altered without their consent.
- Increased appearance of advertisements or pop-ups
- Changes in browser settings or homepage
- Slow system performance or increased resource usage
- Unfamiliar programs or icons on the desktop or start menu

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 |
|---|---|---|
| Beijing AoLanDe Information Technology Co., Ltd. | Beijing AoLanDe Information Technology Co., Ltd. | Self Signed |
| Beijing AoLanDe Information Technology Co., Ltd. | DigiCert Trusted Root G4 | Root Not Trusted |

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.- AdAgent.AB
