We have recently come across a suspicious search engine called As it turns out, this is no ordinary search engine as it can hijack your browser’s settings and replace its homepage and other settings. Therefore, we have labeled it as a browser hijacker and recommend that you remove it as soon as the opportunity arises because it has nothing unique or valuable to offer and can only jeopardize your PC’s security with its shady promotional links. There is no telling what this hijacker can include among its search results. Unfortunately, there is no guarantee that the promoted links are safe and malware free.

When this extension is installed on your browser, it automatically changes the homepage and new tab page addresses, and also the search provider. Its creators want you to use it as your primary go-to search engine. Our tests have shown that this hijacker does not have its own search algorithm. Therefore, it redirects all entered search queries to a modified Yahoo search engine. It is modified because it features promotional links that you would not otherwise see on the regular search engine. is used for advertising purposes because that is the only way it can be profitable.
