From one persons accusation with no proof, this is enough to flag his account? How did the OP know that the trojan is a wallet stealer? He said his virus protection stopped it. I get viruses sent to my inbox all of the time. I don't immediately think the last person that PM'd me was the one who sent it. Doesn't make sense.
Hmm good point, but combined with certain other metrics, it does appear that Dragonkid is highly likely to be a scammer.
Do you even know if he traded anything ? If you can include the post where he said the things the OP is claiming, that would make the situation more credible.
