I recently just added ZoneAlarm (latest version) to my Home XP, and everytime I turn on the computer it asks me if I should let Windows Explorer access the net. Why does Explorer need net access. And about 20 minutes later, Service.exe requests to go online. I use updated AVG and online Trendmicro for virus scans, and use updated Spybot for spyware removal. Why and what are these things that are asking for access. I have a Dell 5100 laptop that I think may be the service.exe, but nothing happens when I refuse access for both Windows Explorer and service.exe.

Thanks in advance for your help!
