Earlier this morning I opened Skype, signed in as available, and left it standing by without ever using it. Later on, I closed it on the desktop, but I forgot that it stays open and hidden in the system tray.
I came back to the computer a couple of hours later and noticed the Send and Receive LEDs on the cable modem were burning up the information highway. I closed the only open application, MS Word, and it wasn't that. I opened perfmon.exe, the windows resource monitor, and looked at the network tab. You can see the Skype activity in the screenshot:
Anybody recognize that smartbro.net URL or have any idea what may have been going on? I will scan for malware in the meantime.
Do you think it's likely that someone could have been going through my files? With as many writes as reads, there was a lot of information going upstream.
I have a backup image from two days ago I can restore, but I haven't found any malware. If someone was collecting my stuff, it's too late to do anything about it now. I don't think they could get any important passwords. I never store my banking and bill paying info.
