The following bug has been logged online:

Bug reference: 1861
Logged by: Thomas Turn Jensen
Email address: thomas (AT) turn (DOT) dk
PostgreSQL version: 8.0.3
Operating system: Windows XP SP2
Description: Possible Incompatibly with NOD32 AV.
Details:

I'm aware this will not be a "complete" bug report with all neccesary
information. I have not tried to reproduce the problem but am satisfied I
found a solution. The reason I make this bug report is a result of someone
(rightly) saying "im not sure who you would mail but i think it needs
documenting.." after the fact. Since I know of no better means of
documenting it, I use this approach.


PROBLEM:
After installing NOD32 antivirus (www.nod32.com) PostgreSQL no longer
works.

SYMPTOMS:
Any application trying to connect/log into PG freezes. Only a termination of
the PG service will unfreeze the applications with an error about unexpected
EOF from socket (or something to that effect. Sorry, I don't have the exact
message).

Log in pg_log/postrgresql-#date-#postfix contains the following entries for
every frozen application:
2005-09-03 02:46:11 LOG: could not receive data from client: No connection
could be made because the target machine actively refused it.
2005-09-03 02:46:11 LOG: incomplete startup packet

POSSIBLE MITIGATING FACTORS:
NOD32 was installed together with PC-cillin 2002 (AV). However only NOD32
was active. Disabling NOD32 did not have any effect.
"Google Desktop" reports possible conflicts with NOD32.

WORKARROUND:
After uninstalling NOD32 and rebooting, PG works as expected.

SELECT version():
PostgreSQL 8.0.3 on i686-pc-mingw32, compiled by GCC gcc.exe (GCC) 3.4.2
(mingw-special)

TIP 1: if posting/reading through Usenet, please send an appropriate
subscribe-nomail command to majordomo (AT) postgresql (DOT) org so that your
message can get through to the mailing list cleanly

I would contact the people who created NOD32, give them the URL to
pginstaller, and tell them it breaks PostgreSQL.
