What is Screencastify

Screencastify is a legitimate extension with over 10 million downloads in the Google Chrome store. It is a truly great tool embracing the feature of screen recording without using desktop applications. You can record, edit, and share a video right in a browser, which makes Screencastify the most convenient recording tool to use. Unfortunately, some users complained that Screencastify conflicts with the Lockdown Browser, which is a browser developed by Respondus and meant to grant a cheating-free ground for running exams within education. The problem is that people cannot access the Lockdown browser when Screencastify is on. This constrains users to either disable or delete the extension from their browsers. Whilst this can be frustrating, the problem will persist until developers resolve incompatibility themselves. For now, removing/disabling Screencastify remains the only feasible solution. If you do not know how to do so, we will help you make it work in the article below.


How Screencastify gets on your computer

Besides being in the Chrome Store, Screencastify can be promoted and included in third-party repacks. This means that some users may install it unwillingly when running the setup of another program. As a result, they do not understand why some of the things stopped working like LockDown Browser. Moreover, some programs delivered as optional offers can seed special values that restrict users from performing manual removal. The easiest way to prevent the installation of unintended software is to deselect additional offers inside of “Advanced” or “Custom” sections. Although Screencastify is not a virus, it can be abused by cybercriminals as a cover to install unwanted software without your consent. Be careful and download software only from trusted and well-known resources to avert such consequences. Read our guide below to learn more about online protection and the removal of Screencastify.
