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.

The KuaiZip software comes from China and is offered as an archive utility for users that like the design of Windows 10 and would like to see it incorporated into their apps. The KuaiZip software is promoted at Kuaizip.com to uphold the design principles of Windows 10 and allow users to manage their archived data efficiently and beautifully. The KuaiZip program boasts of featuring high compression ratio, compatibility with a broad range of data containers, and low resource consumption. With a size of 7MB and a sleek interface, KuaiZip may attract many users to install it. You should know that KuaiZip is supported by a large pool of marketers and may show many advertisements on your screen. Additionally, Kuaizip.com is hosted on several IP addresses that are associated with cyber threats like Pinfi and Genome.
The KuaiZip application may enable users to make, edit, move and transform archives in formats like 7Z, ZIP, RAR, ARC, LBR, TAR, BZ2, IZO, GZ, and APK. However, most users may not welcome the KuaiZip app that comes from software developers that fail to protect their Web site. The KuaiZip tool is perceived as a Potentially Unwanted Program (PUP) that may expose users to cyber threats and load unprotected marketing content on their screen. The ads by KuaiZip may include links to blacklisted domains and invite users to install riskware such as GoFastPC and IB Updater Service. The KuaiZip program is similar to ZiperFly and may edit your Registry to become your default archive manager. You may experience difficulties in removing KuaiZip manually because it can run as a background service continuously. You can purge the KuaiZip software with the help of a reliable anti-malware utility easily.

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 |
|---|---|---|
| Fashion Cloud Culture Media (Beijing) Co., Ltd. | WoTrus Code Signing 2021 CA | Self Signed |
| Fashion Cloud Culture Media (Beijing) Co., Ltd. | WoTrus Code Signing 2021 CA | Self Signed |
Block Information
