Kuaizip

Kuaizip is a file archiver that is meant to help you combine multiple files into one archive file that is easier to store or share. Although this program does work, our researchers recommend deleting it from your operating system, especially if you have downloaded it by accident, without meaning to install it in the first place. It appears that this program is targeted at users in the Chinese market because it is represented in Chinese via kuaizip.com and kpzip.com websites. These websites are automatically blocked by Mozilla Firefox and Google Chrome browsers, which, of course, is a red flag. How can you trust websites and the installers represented via them if your browser is telling you that they are unreliable? So, what is the danger you might face if you download and use this suspicious app? Continue reading, and maybe you will decide to remove Kuaizip as well.

Our researchers classify Kuaizip as a potentially unwanted program, mainly due to the fact that it can install itself without your permission and because it might introduce you to a bunch of unfamiliar programs. It was also found that there are several different versions of this PUP. One of them – the English version – could be introduced to you by unpredictable third-party installers that could bundle it along with unknown software. The second version, which is the more common one and is available from the official download page, is represented in Chinese, and it can be installed silently. Once installed, this program can automatically set itself as the default archiver, and that is done illegally, which, of course, is a sign of malicious activity. This version might also be installed onto your computer by malicious installers. Therefore, if you discover Kuaizip on your PC, we suggest you scan your computer to see if other threats deserving of removal are active as well.

Although Kuaizip might work as a fully functional archiver, it certainly does not work better than popular authentic and reliable tools of its kind. Considering that it does not offer exclusive, irreplaceable services and that it is not trustworthy, the cons outweigh all the pros that you might believe are associated with this app. Of course, if it was installed with your permission, and you were able to decline all additional offers, it is unlikely that you will see it as a threat. However, if it installs itself without permission, feeds you false information, or lets in other suspicious, potentially dangerous programs into your computer, you cannot treat it as a harmless piece of software. Another thing you need to consider is that Kuaizip is capable of connecting to the Internet without your permission. Whether this connection is used to transfer information about you, monitor the application, or download components (e.g., updates), this is a security backdoor that cannot be overlooked.

If you uninstall Kuaizip via Control Panel, many components of this potentially unwanted program will remain present on your operating system. Although we could provide you with the list of leftovers that you would need to eliminate if you chose to uninstall the PUP, we offer a different removal method. This method, at first sight, might seem intimidating, but the guide below was created in a way that even inexperienced users should be able to successfully eliminate the PUP. Of course, if other threats are active, you need to evaluate them to see if you are able to get rid of them manually. If you find that you lack experience or time to clean your operating system yourself, we suggest you use a trusted malware detection and removal to have all threats and Kuaizip deleted automatically. Now, if you are having difficulties with the removal – whether you follow the guide below or use automated removal software – we welcome all questions in the comments section below.
