hello all,

I didn't know where else to put this post so here I am. Recently I've noticed that my Local Area Connection icon (the one with the two blinking computer screens) in the systray is constantly blinking. Yes, even when I'm supposedly not doing anything, any kind of network activity. I'm not transferring anything, I've certainly not got any web browsers opened up. I've noticed this just now and I'm sure I didn't have this happen up until a few days ago.

I'm trying to figure out why that's happening and I can't help but think that there maybe something lurking or worse someone lurking on my system.

I've got my antivirus (avast) running and definitions upto date, it's not complaining. Although, around when I noticed this, I did get a warning of some file trying to execute which was infected by some Win32 trojan. It said it was 'Win32:Trojan-gen {Other}'. I simply deleted the file. Perhaps part of it did manage to infect? I don't know.

Are there any good free tools out there that can detect network traffic/activity and produce for me some sort of data that shows me where the connections are being established to? Kind of like the logging you find built into your router's web interface.

Anyway, I am just curious of the mystery behind the blinking LAC lights. I'd like to hear your thoughts on what you think it might be.

thanks all,
a

Do you have a firewall in place? A good firewall should notify you of any new programs trying to access the internet, plus should have logging/reporting capabilities that might show you if there's any new or unusual activity. I suggest you visit this link. Follow the instructions there and see if they help. If you're concerned that you may have additional infections, it would be a good idea to post in the Malware removal forum (don't post any logs in here, please).
