How to remove SpeedKnow virus

SpeedKnow is a website associated with a potentially unwanted program (PUP) that installs onto a computer without user consent and knowledge or by use of deceptive advertising.

The SpeedKnow website contains a free tool that can test your internet speed. There are many websites like these. In reality, they are essentially full-screen advertisements. Adware, malware, and potentially unwanted programs (PUP) will infect your computer and redirect you to this website. The website contains advertisements and information about you such as your IP address, ISP, screen size, recent search terms, organic information, and more. This allows the party to generate revenue through advertisements on the website and by selling your information.

SpeedKnow virus is known to infect a PC or laptop computer with other malware, adware, spyware, rogue software, and malicious files. This means that if your internet browser randomly opens on a SpeedKnow website or your browser randomly redirects to a SpeedKnow website when you browse the web it is guaranteed that your computer is infected with other malicious programs.
