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.

SpeedMaxPC Image
SpeedMaxPC is a rogue computer optimizer and utilized to abduct money from newcomer computer users. Like other rogue security programs, SpeedMaxPC claims to be a legitimate solution to problems on a computer. However, SpeedMaxPC will actually be responsible for problems such as a decreased system performance and an enormous number of bogus error messages. ESG malware researchers strongly advise computer users to avoid installing SpeedMaxPC on their computer. Criminals profit from SpeedMaxPC by convincing inexperienced computer users that they need to purchase an expensive 'full version' of SpeedMaxPC in order to remove nonexistent problems on the infected computer. It is important to ignore all claims made by SpeedMaxPC and not to purchase a 'full version' of this fake system optimizer. Instead, SpeedMaxPC should be removed with the help of a real security application.
SpeedMaxPC has the capacity to display realistic looking error messages and system alerts on the infected computer. These error messages are very similar to the ones that may be displayed by a legitimate security program. However, they may contain grammatical errors or strange elements that betray the fact that they are not real. The similarity between real security programs and SpeedMaxPC ends here; this fake system optimizer displays completely false information in its error messages, detecting corrupted files or malware that is simply not present on the victim's computer. One important thing to remember about SpeedMaxPC is that SpeedMaxPC will often report problems with legitimate Windows files. Computer users who try to fix this 'problem' by removing the supposedly infected files will suddenly find that their Windows operating system cannot continue normally without them.
Although SpeedMaxPC is marketed as a program that can help a computer become faster and more efficient, SpeedMaxPC actually does the opposite. SpeedMaxPC may cause the affected computer to become slower and crash frequently. This is because SpeedMaxPC does not interact well with other, legitimate programs. It is also important to note that SpeedMaxPC may stop your normal activities by displaying fake error messages quite frequently, making it difficult to use the infected computer normally. This, of course, more than negates any supposed speed increases that should come from using SpeedMaxPC.

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.- Banker.R
