Interesting, the European Commission has proposed to extend the EU consumer protections for physical products to software. If the proposal becomes law, software companies could be held responsible for security and efficiency problems of their products.

Commissioners Viviane Reding and Meglena Kuneva have proposed that EU consumer protections for physical products be extended to software. The suggested change in the law is part of an EU action agenda put forward by the commissioners after identifying gaps in EU consumer protection rules.

A priority area for possible EU action is "extending the principles of consumer protection rules to cover licensing agreements of products like software downloaded for virus protection, games, or other licensed content," according to the commissioners' agenda. "Licensing should guarantee consumers the same basic rights as when they purchase a good: the right to get a product that works with fair commercial conditions."
