Thank you in advance for any answers offered. 1. Whilst running the common ports checker on TDS 3 I saw that the only connection was port 139 - all others failed. Yet when I closed 139 my internet service failed so I had to reopen. My next move was to test the firwall and it came up stealth but am I vulnerable? I am running TDS3, PG, EWIDO, ZA, NOD32, SB, SBS&D, Adawre... 2. There is a post on here somewhere where a moderator posted a bunch of programs that he/she uses to keep his system tight. I have searched for it but to no avail - does anyone know the link to that post? Once again thanks to anyone who offers an answer and many thanks to the wonderful people who provide such excellent service at DS.
