Hello.
I believe I have a rouge Pc on my network that been "bot 'ted" and is sending out spam, but is there and app / technic that will allow me to work out which device ?
I have lock port 25 down on my firewall so only the Exchange server and sent thought it (so the ISP is not putting us in their Tar Pit any more, and the spam is not being sent out any more ), but I need to find the device and eradicate the virus / bot etc. that is causing the spam .
Does any one have any advice ?
thanks
