KuaiZip Description


KuaiZip may not be a reliable tool that can help you compress or decompress your files. It is a Chinese Potentially Unwanted Program (PUP) that may not perform as expected. Moreover, it may cause unpleasant modifications to other applications like your browsers. It is true that the license of KuaiZip is free, but its developers may benefit financially from its existence. The PUP may inject additional commercial materials in the sites to transfer you to its partners. This way, the creators of this unreliable compression software may collect pay-per-click commissions. You should keep in mind that there is no way to know if all of the sponsored domains are safe. Some of them may try to deploy threats or other PUPs. You may even end up on platforms designed to gather information from the visitors exclusively. The targeted data may include your phone number and email address, which may result in spam. For this reason, the experts recommend you not to click on any pop-ups, banners, sponsored videos or in-text ads by KuaiZip.

Unfortunately, the mere existence of these commercial materials may cause trouble. The constant loading of multimedia ads may become a burden to your Web clients. As a result, Google Chrome, Mozilla Firefox and Internet Explorer may start working sluggishly. Your surfing sessions may get interrupted by some speed drops or freezes as well. KuaiZip may change some of the settings automatically. It may replace your homepage and default search provider with untrustworthy alternatives associated with manipulated results. There are two main methods for this PUP to enter your system. Some users may download it willingly from one of its official sites, which are kuaizip.com and kuaizip.com/en. The product description there states that KuaiZip is better than established programs like WinRAR, 7-zip and WinZip, which is a lie. If you cannot remember installing this PUP manually, then it probably came in a software bundle. You should consider deleting the suspicious application with a renowned anti-malware tool.
