What is Undefined.com?

Undefined.com is classified as a browser hijacker, because it can alter your browser settings. Once it takes over, the hijacker adds its files to your PC and its extension to your browsers. It monitors your online behavior and floods you with different types of ads. The hijacker also causes constant redirects to its sponsor webpages. The reason this happens is because it is aimed to boosting online traffic. There is no way to avoid the hijacker’s symptoms, because it affects all web browsers.
