OneClick ( – is a usual ad-supported program, which claims to improve your search experience. It can be installed on the most popular browsers, such as Google Chrome, Mozilla Firefox, Opera, Edge with Internet Explorer. But even if it is more convenient to search with this extension, it can be really harmful to your PC. It shows a lot of ads on every website that you visit(banners, videos, pop-ups, in-text links) and redirects users to sponsored websites, that are very suspicious. These ads may look as a real one and from trusted resources, but they are definately not. That is why we recommend to remove OneClick ( from PC.
