Hi,

y'll find explanations about TCP445 port here:
http://www.ntsecurity.nu/papers/port445/

How to remove listening on this port?
You can close it by modifying the registry in the following way:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters ]
"SmbDeviceEnabled"(DWORD)=0

Then restart.

You need a firewall, ipsec filtering, or ip filtering to block access to ports on a
computer. Port 445 is used for a lot of things including file and print sharing. If
your computer does not offer shares to anyone or needs to be managed remotely via
Computer Management, disable file and print sharing on your network adapter. The link
below gives the basic steps on computer security. I would be sure to run a virus and
spyware scan ASAP using current definitions. --- Steve
