OpenDNS

OpenDNS is a large company registered in San Francisco, California. It offers a software that goes by the same name and comes in both free and paid versions. Allegedly, the purpose of their tool is to protect you from malicious and potentially fraudulent pages. Moreover, various institutions such as schools may use this application to prevent the loading of inappropriate websites. Although the company is legitimate, the free version of their software may be categorized as a Potentially Unwanted Program (PUP). The cyberspace is full of user's complaints about some persisting and annoying advertising materials that contain the logo of OpenDNS. The firm claims that these commercial materials are not caused by their software, but this statement is rather doubtful. In their ''Terms and Conditions', the application clearly explains that it may link the user with various third-party sites. What is more, they explicitly state that they cannot be held responsible for any damage that may occur. This fact means that for your own safety, you should never click on the ads displayed by OpenDNS. They may come in various formats such as pop-ups, banners and interstitial ads, and you may face them consistently throughout your surfing sessions. The PUP also may change the homepage of the users without any approval to guide.opendns.com. This low-quality search engine borrows the results from the legitimate search platforms but includes multiple sponsored links in them. Many users complain that OpenDNS may block some sites that are known for sure to be safe. Such actions may cause significant inconvenience to the user. Other clients report that they cannot locate and delete OpenDNS manually. For this task, you should use some advanced anti-malware tool.
