Subject: Lots of traffic on port 1472 from explorer

Guys,

thanks a lot for the tips, indeed there was a KLP keylogger.

I removed it, but it seems that something else is amiss,
I still see lots of traffic from explorer.exe on the 1472 port.

The traffic is indeed coming from a system I have control of,
I still have no dumps though. I can see nothing worrying apart
from the aforementioned keylogger which has now been removed

Lots of data is transferred from my computer to the outside world,
pretty much all to addresses in the 35.xx.xx.xx range on the
microsoft-ds port. Huge amount of short lived connections.
I thought it looked like worm activity but I might be wrong.

Thanks!
