Hi,
i have two local trojan ports open. I found that using LPS program. The
ports are 80 and 110. I have winXP firewall and a router. Can i somehow close
this two ports only by using xp firewall?

Thnx a lot.
 
At the initial stage use TCPView
http://technet.microsoft.com/en-us/sysinte...s/bb897437.aspx to get the
name of process, which opened the ports. After this you may de-install or
remove applications or put them into black list in XP FireWall

Thanks for reply.
I have licenced copy of port explorer but there, i don't see any mentioned
open local ports. Only firefox.exe is using remote port 80, for 110 i'm not
sure. Thats strange.

a) If it's really a trojan, merely installing a firewall will not help
you

A trojan won't use 80 and 110, the chance of colliding with real
applications would be too high. I'm willing to bet that those two ports
are opened by your virus scanner which is trying to scan your web
traffic and email downloads...

Take my advice, I don't use it anyway.
 
Port 110 is for email.

I don't think so. This is a stupid approach from the point of view of
security software. Antivirus or whatever will try to enumerate all opened
ports, this operation is less costly then binding, and listening on some
port.

Even if the above solution would not be suitable for antivirus, it could
always call bind (...) on a specified port., and if it busy, it will get
WSAEACCES error . So, as you can, see, there is no need to create a fully
functional server to check some port (because listen (...) and accept (...)
are not called in this case)

BTW, what is the need to open 80 port or 110 to scan the traffic? The
traffic which going to be scanned should go to remote IP + remote port. Not
the local ones.

AV software often contains built-in proxy servers that open for example
localhost:110 and alter the email software settings to route the mail
download through the local proxy.

Yes, this may happen as-well, I agree.
