CornerSunshine is a Potentially Unwanted Program whose installation introduces a fancy weather widget to the user's desktop. The weather widget works as expected, and it has the ability to display the current temperature and weather conditions, as well as the forecast for a few days ahead. All weather-related information that CornerSunshine provides is reliable since it uses the services of one of the most popular Web-based weather forecast platforms. While this may seem like a useful utility, we should also inform you that CornerSunshine's installation may lead to the injection of unwanted advertisements in the user's Web browser. Ad-supported software is not threatening, but using such programs may worsen your Web browsing experience, and expose you to irrelevant or annoying marketing content every time you use your Web browser.

The CornerSunshine Potentially Unwanted Program does not necessarily have to be downloaded and installed from its official website. Applications of this sort may often rely on software bundles and other software distribution methods, whose purpose is to offer users to install software they might not have intended to use. Software bundles that include CornerSunshine's installation file may always ask for the user's permission to install this software, but they also may forget to mention that CornerSunshine is an ad-supported application, and its installation always brings advertisements to the user's Web browser.

CornerSunshine's benefits are undeniable, but the fact that it is classified as a PUP and participates in suspicious activities on the victim's computer is also something that can't be overlooked. If you don't use the CornerSunshine's services on a regular basis yet you have it installed on your computer, then we suggest that you remove this software so that its ads will not bother you again. The removal of CornerSunshine can be performed from the Windows Control Panel manually, or users also can use an anti-malware scanner to erase all files and Registry entries that accompanied CornerSunshine's installation automatically.
