Malware in Webpages


Nonfree (proprietary) software is very often malware (designed to mistreat the user). Nonfree software is controlled by its developers, which puts them in a position of power over the users; that is the basic injustice. The developers and manufacturers often exercise that power to the detriment of the users they ought to serve.

This typically takes the form of malicious functionalities.


This page lists web sites containing proprietary JavaScript programs that spy on users or mislead them. They make use of what we call the JavaScript Trap. Of course, many sites collect information that the user sends, via forms or otherwise, but here we're not talking about that.

If you know of an example that ought to be in this page but isn't here, please write to <webmasters@gnu.org> to inform us. Please include the URL of a trustworthy reference or two to serve as specific substantiation.
