On my XP machine, using ZoneAlarm, I dialed onto the 'Net. As soon as I logged on, without even launching any applications, I started receiving lots of bytes. Ultimately, I rec'd about 300K. Can anyone give me a clue as to how to figure out what's going on? I'm a reasonably sophisticated user. I checked to see what processes or programs were running at the time, and the only ones I could find all looked to be OK--standard programs and processes started up at launch. As a matter of fact, some weeks ago I went through the processes launched at startup and disabled most of them. And I don't see any of the classic spyware/adware/malware/scumware programs listed anywhere on my machine. So where are these 300K bytes coming from? Is this related somehow to XP checking automatically for updates etc?
