About Clearsight

A little background of who we are and what are our values and mission

Clearsight Antivirus was founded in 2010 by a group of people with a long background in the software security industry. Our staff have used the experienced gained in other antivirus companies to produce our own unique solutions.

Most users want software security products that keep their computer safe and preferably something they do not even notice until it is needed.

Software piracy is a growing concern for all companies, including us. That is why we wanted to make it simple. Clearsight Antivirus Free, is Free. You download it and you use it. We do not have a hidden agenda there. However if you like the software and you want to support us in our mission to provide you with the best software possible at a price you are comfortable paying, then please consider upgrading to the Premium version.
