I'm using the latest build of NS. I've been developing applications in our family business for about 25 years. The following has never happened before:
I was testing a relatively simple application that I've developed using Delphi with several additional well-known component libraries. The program accesses data files that are shared on our local P2P network. Upon completing a simple connection test and closing the program, Norton threw up an alert of "Suspicious network activity" that was evidently generated as a result of something that my application was doing. At first I thought I needed to tell Norton to give the program access to our local network. Upon closer examination of the alert, however, I became very confused and suspicious myself. Here's the firewall alert dialog:
My app's name is etime.exe; my pc is M6800WIN81, and the IP address is as shown. My app attempts no connections to any address(es) outside of our local net. In fact the only connections to the local net are handled entirely by Delphi and Advantage Database Server. As can be seen, it appears that my pc is attempting a UDP connection via port 2989 to an external IP for which I can find no information at all. It also appears that my pc is utilizing a port with a negative number??? (-5679) I had no idea that was even possible. In any case, I'm very concerned that this all might be indicating that a trojan or other malware might be attempting to utilize my app for nefarious outbound communications. If that's the case then I can only imagine that the Delphi IDE/compiler/linker has been infected in some way within the last few days. I'm definitely not a Ring-Zero developer so I have no idea how any of this could actually work.
Therefore, I'd be immensely appreciative if anyone might be able to tell me what could cause this type of firewall activity, and whether or not it's likely that I've been infected despite my very diligent efforts to always use safe-surfing practices, as well as having Norton installed and up-to-date since I bought the laptop three years ago.
TIA
