LiteBrowser is a PUA (potentially unwanted application) which is based on the Chromium open-source browser software. This PUA is actually an adware that will attempt to commandeer your browser search and homepage. LiteBrowser will also pop-up unwanted ads and send you to malicious websites to get money from you or infect your computer further. It may also prevent you from changing your settings back.
LiteBrowser is usually installed through bundled software without you knowing. You have to remove it immediately.
