JiSuZip is a Chinese archive program that is installed along with the MaohaWiFi PUP. When JiSuZip is installed it will register itself as the default program for handling archive files on the computer.
While JiSuZip does not display any advertisements, it does modify the Windows configuration so that it becomes the default program when interacting with ZIP or RAR files. As the interface is in Chinese this will make it difficult for those who do not speak this language to properly use the program. Furthermore, JiSuZip does not provide a way to uninstall it.
How did the JiSuZip Adware get on my computer?
The JiSuZip program is installed along with the MaohaWifi PUP. Maoha Wifi is bundled with and installed by free programs that did not adequately disclose that other software would be installed along with it. Therefore, it is important that you pay close attention to license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Furthermore, If the license agreement or installation screens state that they are going to install a toolbar or other unwanted adware, it is advised that you immediately cancel the install and not use the free software.
As JiSuZip is installed with unwanted programs, modifies your Windows settings, and does not provide a way to uninstall it, it is my opinon that you should uninstall it. To remove it and other unwanted programs that may be installed along with it for free, you can use the guide below.
