Our research has revealed that – which is the official download page for the suspicious CornerSunshine – is not currently active. It is possible that this page will be revived, but, at the moment, the creators of this PUP rely on third-party installers for its distribution. It is most likely that you will find this program attached to other, potentially more attractive apps. Unfortunately, you might end up installing malware as well. It appears that the program is very similar to Uncheckit, SOSO DESK, and other PUPs. In fact, it is possible that they were created by the same developer. It is no wonder that these programs are usually found being spread in bundles that often carry the same type of software. Our researchers warn that adware and browser hijackers could be packaged along with CornerSunshine.,, and are few of the many browser hijackers that you might face. Obviously, if you find your browsers hijacked, you need to delete malware as soon as possible. In general, it is a good idea to scan your operating system when you discover the PUP just to assess the situation. If you discover more dangerous threats, you might need to take care of them first.

According to the Privacy Policy – surprisingly, is still up – the suspicious CornerSunshine can start collecting personal information as soon as you install it. If that was not bad enough, the PUP also can expose you to surveys and promotional content. Using personal data, it can approach you with much more personal, attractive offers, and that is dangerous. If malicious parties get involved, they could use the information collected about you to introduce you to scams, and this could lead to many security problems. For example, you could get scammed into disclosing even more sensitive data, visiting unreliable websites, downloading unreliable software, or purchasing useless services. Although we cannot claim that you will face all of these issues, do you want to take the risk for a weather forecast? We are sure you do not, and that is why removing this potentially unwanted program is a good idea.
