Been posted on other forums re: This exact same problem.
From what little I've read, it seems it's definately a trojan/keylogger/whatever to get your Neteller info. Whether or not 24hr poker is in collusion on this, I have no idea; BUT it does seem awful suspicious as they'd need further information/ID to cashout.
Or maybe they're preying on the fact that 24hr poker is clueless and doesn't answer support mails (again read other posts), and getting the money in and out before they know what's going on. *shrug*
