I can't find a list of blacklisted products

I checked the Securom site but it makes the Starforce website looks user friendly
For blacklisted products I’d say Any CD/DVD emulation software, Any CloneCD/DVD type software and any of the older virtual drive hiding software (not so sure about this one)
Just look for any software that “installs” (not just the exe) and you've used in the past to get round gay backup protection.
Sidenote: after a good search I came up empty on Securom 7 removal tool too, if SR7 works the same as Starforce shouldn't there be a way to remove it incase there is compatibility problems...
