Threat Scorecard
EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Popularity Rank: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

Your system has been detected with a potentially unwanted program (PUP) known as PUP.Optimizer Pro. This detection indicates that your computer may be affected by a program that is not malicious in nature but can still cause issues with your system's performance and security. It is essential to understand the nature of this threat and take appropriate steps to remove it to ensure your system's integrity and safety.
Table of Contents
What Is PUP.Optimizer Pro?
PUP.Optimizer Pro is classified as a potentially unwanted program, which means it is not considered malware in the traditional sense but can still have undesirable effects on your computer. PUPs are often bundled with other software or installed without the user's full knowledge or consent. They can consume system resources, display unwanted advertisements, or collect user data without permission. The primary goal of such programs is usually to generate revenue for their creators through various means, including affiliate marketing, advertising, or selling user data.
How PUP.Optimizer Pro Operates
PUP.Optimizer Pro, like other PUPs, operates by integrating itself into your system and potentially altering settings or installing additional software without your explicit consent. It may claim to offer benefits such as system optimization or enhanced performance, but in reality, it may not provide the promised services or could even degrade your system's performance. PUPs can also compromise your privacy by collecting personal data, including browsing habits, search history, and other sensitive information, which can then be sold to third parties or used for targeted advertising.
Symptoms of Infection
Symptoms of a PUP.Optimizer Pro infection can vary but may include an increase in unwanted advertisements or pop-ups, unexpected changes in your browser's homepage or search engine, slowdowns in system performance, or the presence of unfamiliar programs in your list of installed applications. You might also notice that your browser settings have been altered without your consent, or you are being redirected to suspicious websites. These symptoms indicate that your system has been compromised and that you should take action to remove the unwanted program.
How to Remove PUP.Optimizer Pro
- Boot your computer in Safe Mode with Networking to prevent PUP.Optimizer Pro from loading and to give you a clean environment to perform the removal.
- Use a reputable anti-malware tool, such as SpyHunter, to perform a full scan of your system. This will help identify and remove all components of PUP.Optimizer Pro.
- Manually uninstall any suspicious programs that you believe may be related to PUP.Optimizer Pro. Be cautious and only uninstall programs that you are certain are malicious or unwanted.
- Reset your web browsers (Google Chrome, Mozilla Firefox, Microsoft Edge, etc.) to their default settings to remove any changes made by PUP.Optimizer Pro, such as altered homepages or search engines.
- After completing the above steps, reboot your computer and perform another full scan with your anti-malware tool to ensure that all remnants of PUP.Optimizer Pro have been removed.
Conclusion
Removing PUP.Optimizer Pro from your system is crucial to maintaining your privacy and ensuring your computer operates efficiently. By following the steps outlined above, you can effectively remove this potentially unwanted program and protect your system from similar threats in the future. It's also important to be cautious when installing software, always choosing the custom installation option and carefully reading through the terms and conditions to avoid inadvertently installing PUPs. Regularly scanning your system with reputable anti-malware tools and keeping your operating system and software up to date can also help prevent infections.

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 |

Block Information
Block Information
During analysis, EnigmaSoft breaks file samples into logical blocks for classification and comparison with other samples. Blocks can be used to generate malware detection rules and to group file samples into families based on shared source code, functionality and other distinguishing attributes and characteristics. This section lists a summary of this block data, as well as its classification by EnigmaSoft. A visual representation of the block data is also displayed, where available.| Total Blocks: | 874 |

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.- SProtector.C
