"Sony (the owner of SecureROM copy protection) is still up to its old tricks. One would think that they would have learned their lesson after the music CD DRM fiasco, which cost them millions. However, they have now started infesting PC gaming with their invasive DRM. Facts have surfaced that show that the recently released PC game BioShock installs a rootkit, which embeds itself into Explorer, as part of its SecureROM copy-protection scheme. Not only that, but just installing the demo infects your system with the rootkit. This begs the question: Since when did demos need copy protection?"
If you have installed BioShock on your PC, then you will want to follow the alternate link to use Microsoft's Rootkit Revealer to check your PC for malware infection.
The 2nd Alternate Source ("BioShock Demo Installs SecuROM Service" at GamingBOB.com) has issued a retraction, claiming that SecuRom does not install a rootkit.
