How to uninstall KuaiZip virus ads

3 min read
If the KuaiZip application has ended up on a PC, removing it is a necessary security measure as it displays annoying ads and promotes other malicious software.

Using the KuaiZip software is a mixed blessing. On the one hand, it claims to archive data with higher compression ratio than competing tools WinRAR, WinZip and 7-Zip do. According to this app’s official web page, its merits also include support of more than 40 popular formats, ability to work with virtual hard disks without using virtual machine, and more. Plus, it’s free to use. However, the ostensibly all-embracing feature set of KuaiZip has got a flip side. Users who install it start experiencing issues with obnoxious ads that pop up from the system tray and flood visited web pages. These advertisements recommend victims to install some crappy software, possibly malicious, or go to certain sites that may host malware.

The biggest impact encountered by those infected is in the way web browsers operate. Whether a user navigates to an ecommerce site, blog or their favorite news resource, it will be crammed up with comparison shopping items, coupons, freebies and other types of adverts. A particular nuisance is interstitial advertising that also occurs due to the interference of KuaiZip. Full-page transitional ads will be automatically opening up in the background, causing the affected browser to run slower. The unwanted program also tends to embed numerous in-text links all over web pages, which can be clicked accidentally and spawn yet more junk in separate tabs or new browser windows.

On top of that, KuaiZip is likely to generate dialogs that strongly recommend the victim to install some product in order to enhance computer performance or address security issues. For instance, these alerts may wrongfully state that the system is at risk due to spyware or Trojans, while in fact the only troublemaker is the compression tool in question. Notifications of this sort are deceptive and should not be taken for granted, otherwise more infections may slither their way into the target PC. Not only are these popups and splash screens annoying enough to interrupt the user’s normal computing routine, but they also ending up becoming a resource hog that deteriorates the overall functioning of the machine. Yet another side effect of KuaiZip is that the victim may be unable to open and use other programs, especially antimalware suites that could flag the impostor as a malicious entity.

The way this controversial utility propagates is nothing out of the ordinary. It clings to third-party applications by means of bundling, a technique that allows distributing arbitrary software alongside harmless-looking free programs, such as media players, hardware drivers, or online video converters. So users should treat freeware installation clients with a bit of paranoia and always go the custom setup route rather than the default (recommended) option. When it comes to removing KuaiZip from a computer, regular uninstall methods may be inefficient. The best way to go about this issue is to follow a specially crafted adware elimination procedure.
