I thought the name Codex sounded familiar. At least their DIRT program worked, even though it was just a high priced trojan. You can actually download DIRT for free from the internet. Just don't get caught with it, because it is illegal to own in the private sector. There is also a cracked version of DIRT online, which allows full use, but like I said....

Knowing Codex, they probably got ahold of the Optix trojan source, and just made a couple small modifications, closed the source, and sold it for lots of cash. Its amazing what an "ex-cop, convicted fellon" who did time for invasion of privacy using computers if I remember correclyt, can do with other peoples source code
