PUP.ZoomInfo

The detection of PUP.ZoomInfo on your system indicates the presence of a potentially unwanted program (PUP) that may be causing issues with your computer's performance and security. It's essential to understand the nature of this threat and take appropriate steps to remove it to prevent any potential harm.

What Is PUP.ZoomInfo?

PUP.ZoomInfo is a type of malware that is classified as a potentially unwanted program. This means that while it may not be as harmful as other types of malware, such as viruses or Trojans, it can still cause problems with your system and compromise your privacy. PUPs are often installed unintentionally, and they can be difficult to remove without the right tools and knowledge.

How PUP.ZoomInfo Operates

PUP.ZoomInfo, like other PUPs, operates by installing itself on your system and then executing its payload. This can happen through various means, such as downloading software from untrusted sources, clicking on suspicious links, or opening malicious email attachments. Once installed, PUP.ZoomInfo can collect data about your browsing habits, search history, and other personal information, which can be used for targeted advertising or other malicious purposes.

Symptoms of Infection

If your system is infected with PUP.ZoomInfo, you may notice several symptoms, including slowed system performance, increased pop-up ads, and changes to your browser settings. You may also notice that your search results are being redirected to unfamiliar websites or that your system is crashing frequently. Additionally, you may see suspicious programs or toolbars installed on your system that you don't remember installing.

• Slowed system performance
• Increased pop-up ads
• Changes to browser settings
• Redirected search results
• Frequent system crashes
• Suspicious programs or toolbars

How to Remove PUP.ZoomInfo

1. Restart your system in Safe Mode with Networking to prevent PUP.ZoomInfo from loading and to allow you to download and install removal tools.
2. Download and install a reputable anti-malware tool, such as SpyHunter, and run a full scan of your system to detect and remove PUP.ZoomInfo and any other malware that may be present.
3. Uninstall any suspicious programs or toolbars that you don't remember installing, as they may be related to PUP.ZoomInfo.
4. Reset your browser settings to their default values, including Chrome, Firefox, and Edge, to remove any changes made by PUP.ZoomInfo.
5. Reboot your system and run another scan with your anti-malware tool to ensure that PUP.ZoomInfo has been completely removed.

Conclusion

Removing PUP.ZoomInfo from your system requires careful attention to detail and the right tools. By following the steps outlined above, you can help ensure that your system is free from this potentially unwanted program and any other malware that may be present. Remember to always be cautious when downloading software or clicking on links, and to keep your anti-malware tools up to date to prevent future infections.

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
Zoom Information Inc.	DigiCert EV Code Signing CA (SHA2)	Self Signed
ZoomInfo Technologies LLC	DigiCert Trusted G4 Code Signing RSA4096 SHA384 2021 CA1	Self Signed
