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 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.

The BestZiper software that you may be invited to install via a free software package is deemed as riskware and Potentially Unwanted Program (PUP). The BestZiper program does not offer ownership information and valid digital signature. The tool is promoted as a viable alternative to apps like 7Zip, WinRAR and WinZip. The BestZiper app may enable users to open, pack and extract data in the 7ZIP, RAR, ZIP and TAR file formats. You can install BestZiper via freeware packages only and its site on bestziper.com features misleading information. There are no contact details at bestziper.com, and the marketing pitch says:
'WinZip is trusted by millions of businesses and consumers to boost productivity, simplify file sharing and keep information private. The world's number one compression and encryption software, WinZip offers apps for all of today's most popular platforms and devices, giving users a better way to exchange files in the cloud, email and social media.'
As you can see, the text above does not cover BestZiper, and it is a blatant copy/paste of text on winzip.com/about.html. The site is dedicated to an archive manager named WinZip, which is developed by the Corel Corporation and has nothing to do with the BestZiper software. Apparently, the Web designers responsible for bestziper.com have no regard for fair completion and copyrights. There is little or no viable information uploaded to bestziper.com regarding the functionality, purpose, and origin of the BestZiper software. PC users that have installed the BestZiper tool have reported that the main program window may include advertisements in the form of banners. Additionally, the BestZiper appears to run in the system background and might show notifications in the tray area, which refer to ad-supported programs and limited-time deals on online stores.
Computer security experts summarized that the BestZiper software is an ad-supported program with dubious origin and distribution mechanism. The ads brought by BestZiper may include links to unreliable online shops and misleading information. The BestZiper app does not compare favorably to alternatives like 7Zip, and PC users may not find it very helpful. You may want to take into consideration that the BestZiper app may record information like your Internet history and downloads log to help affiliated advertisers deliver personalized offers to your desktop. By installing a reliable anti-spyware instrument, you can remove BestZiper safely.
