I've just removed this improper signature (W97/Marker) from the database
(it was in viruses.db2 file).

Thank you, Adam, for the report and the sample.

BTW, folks, there's a new virus in the wild since today (oh,
already yesterday): Trojan.IRCBot.M (alias W32.IRCBot.B,
Win32.SdBot.18976, Backdoor.IRCBot.gen etc.).
We have received several submissions with it.
So please update your databases.

And you need not submit next samples :-), we have enough of them :-).
