If you downloaded TraderCoin earlier today: it's a VIRUS.(don't get confused with TradeCoin, that's another coin)
My virusscanner didn't catch it (Eset NOD32).
I never run new clients on my main computer, except for today (was in a hurry) and got punished for it.
Why this topic? Saltypistoon deleted the thread about TraderCoin, so someone who already downloaded it might not know it's a virus.
How to remove it:Startup in safe mode, look in your temp folder if you think you are infected (C:\Users\UserName\AppData\Local\Temp)
If you got infected, there should be a qblt.exe, crss.exe, pic0.tmp and something like "afsdsjk" with about the same date and time stamp.
Also remove the client folder and the tradercoin folder in "roaming" (though I think it does no harm to leave it there).
The "afsdsjk" file is a plain text file with the logged keys, edit it in notepad to see if they got your passwords. They didn't in my case, didn't type much while away for work.
Delete all the files in temp after you find them there, just to make sure.
After deleteing the virus, my PC gave me blue screens so I restarted again in safe mode and did a system restore to a point before I got infected.
Warning: don't change passwords on the infected computer before you are 100% sure you got rid of this virus!
