The Error Detector is a handy tool that will supposedly help you “find alternative paths and information on errors”. However, this browser extension is actually an adware that will attempt to commandeer your browser search and homepage. The adware will send you to malicious websites to get money from you or infect your computer further. It will also inject unwanted ads to search results and sites you visit, and may prevent you from changing your settings back.
The adware Error Detector is usually installed through bundled software without you knowing. You have to remove it immediately!
