BestConverterz is a browser hijacker because it changes the most important settings like the homepage, new tab address, and search engine. Users are forced to use a search engine that is unreliable, can misinform them, and lead to dangerous pages. While using this extension or having a potentially unwanted program[1] installed that is responsible for the changes, users risk suffering from monetary losses or downloading other PUPs or even malware.
