I've run into a couple of Visual Basic trojans in the last few weeks that
are sending a list of the client's drives' files to the hacker's machines.
They've both connected at times the machines were untended and transmitted
over 10Megs of data.  Unable to trace the virus (neither machine was
protected) but in both cases a logfile was left behind by the trojan
showing the connection, timestamps and amount of data transmitted.
Unfortunately, the recieving number/IP wasn't listed.  

Mayhap this is a possibility?
