QkSee is a Potentially Unwanted Program (PUP) whose installation may sometimes occur without the user's knowledge. Furthermore, QkSee doesn't have anything special to offer since it is just an average image-viewing utility that isn't better than the default Windows Picture & Fax Viewer. According to QkSee's official website, their software offers better image loading times, optimized resizing, an attractive and easy-to-use interface, as well as compatibility with a long list of image formats. However, all these claims are over-exaggerated, and users who install QkSee will not see any major improvements.

A peculiar fact is that the 'Download' button found on QkSee's official website is not working. Reputable and useful applications don't include dead download links on their websites, but this isn't a surprising fact considering that QkSee's favorite distribution method is software bundling, and very few people would visit QkSee's page to download the application. Software bundles are a commonly used method to monetize freeware applications, as well as to distribute less-known software to more people. Software bundles usually offer users the option to opt-out of the installation of QkSee, but many users might accept the offer and install QkSee on their computers mistakenly. When installed, QkSee may set itself as the default image viewing application, as well as launch a background service (QkSeesvc.exe) as soon as Windows is loaded.

If you don't find QkSee useful, then it is best to remove this application from your computer. The application is safe and uninstalling it via the Windows Control Panel should not leave any files behind. However, if you want to be 100% sure that QkSee was removed successfully, you should use an anti-malware scanner to erase it.
