Oddly enough I can not find any reference in this Starforce FAQ that the Star force Virtual IDE protection Drivers:

1. Open up Ring 0 access to Ring 3 users on XP. (This basically allows any third party application, trojan, viri. Full super user access to your system as a level which is of higher control than your Anti Virus/ Anti Spy ware or Software Firewall.

2. Those of you that are aware of XP's DMA issue will also be aware that anything that interferes with the packet transfer during the reading or writing of a CD/DVD will cause XP to read this as an error. The results of which, each time this occurs XP steps down the DMA speed until it eventually reverts to 16 Bit access. Rendering the drive virtually unusable. Virtual Drives such as those used in Nero will trigger this if starforce is installed.Uninstalling the CD/DVD drivers and the IDE controllers from the Devive Manager and rebooting will normally cure this, however if star force is still present then on certain chipsets the device manager will not find your HDD or CD/DVD drives. Making it appear as if they have failed working. In some extreme circumstances mainly combo drives this stepping down can cause actual hardware failure.

3. The EULA does not cover malicious intent. Starforce are aware of the two previous issues yet have done very little to resolve them. Excluding trying to claim they do not exist.

I would point out that I am a developer with 25 years experience in the business. So when I make comments I make very sure I have fully researched what I am talking about.
