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
