Hi Nick,

I (personally) don't think that is enough.  If the box was rooted,
there could be bots (i.e. other processes) sending outbound email.
Those processes could be persistent or periodic, and they could be
additional services or sub-processes of known-good services.  Further,
the bots could be dynamically loaded via on-box applications (i.e.
Internet Explorer, Firefox, etc.)

You would need an off-box firewall to successfully block outbound SMTP
connections.  With most, if not all, rooted boxs there really is no
safe way of securing it.  Your best path forward is to (IMHO) buy an
new harddrive and start from scratch, manually copying only known-good
files to the new drive, preferably using an intermediate box to virus
scan each moved file.

Best wishes,

-Jim P.
