In case you haven't heard about this in the past day or two, some Sony/BMG CDs that have DRM on them that installs a rootkit on your computer that is nearly impossible to get off. Details are here. Not only does the software install said rootkit, but one could very easily (we're talking script-kiddie easy) use the naming convention to design their own rootkit. And, of course, nowhere in the EULA does Sony/BMG mention that they are, in essence, compromising the security of your computer. They also do not mention that forcible removal of the software (deleting the files manually, since there is no uninstall option provided) will disable your optical drive unless you happen to know how to disable lower filters through the Windows registry. Speaking of Windows, there is no way that creation of such software does not violate the Windows EULA. Unless First 4 Internet, the company who wrote the software, is using all OSS software, they have agreed to Microsoft's EULA on Windows.
I hope Sony/BMG faces a shitstorm because of this. Intentionally misleading the consumer to install software that ties itself into your optical drives and exposes your computer to severe security vulnerabilities, which is nearly impossible to remove without a very high level of technical knowledge or a reformat of your system drive, is wrong and shouldn't be legal.
