So, a description:

I was chatting with my friend, when suddenly a message appeared in the window, as that, I wrote the message, but I know, that I didn't. In a normal chat, there was a message like f*** you in hungarian after my name. I beleived, that that's a virus, but the messages were in connection with my messages, and contained mistakes. After I get know about he is a man, I talked with him, so it's sure, that it's not a virus. I started a packet schniffer, and I saw, that the message, contains his message (as my message) came from the messenger's servers. So, that's sure, that the bug is not in the client, and nobody broke into my machine.
