Copy Protection rootkit installed via Sony DVD "The Cave"

Required for certain programs to run, but may lead to unexpected behavior
Seems to be necessary for Windows 7 to boot. Mine became corrupted, and then my Windows 7 system was dead.
It´s revised by windows 7 during the boot, stoping the boot if the digital signature is not verified. In my case, related with the installation of Skipe. Now the driver is renamed (*.sy instead of *.sys), and the machine is working OK)
