Emergency - postgre is not working

Hello,

I recently updated my norton anti-virus and norton goback - and up until
then - everything for my sambc was working fine now when I try and open
sambc and I received the error message:

X 2006-07-09 22:09:19 [CORE] Connection to database failed (could not
connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?

I went to the postgresql.conf and I added *listen_addresses='*' *under
the # CONNECTIONS AND AUTHENTICATION section.

It still did not work:

When I tried to start the server - I got the error message -

Failed to start server pgsql-8.0 Errcode = 1069

I also noticed that when I start windows xp - that I have two accounts
owner(administrative) account and postgre account. The postgre account
requires a password. The password that is listed on sambc/core.xml file
does not work.

How do I fix the problem and also get into the postgre account?? or remove
the postgre account all together
HELP
