Connecting to Insecure Wireless Networks

[quickques]

I didn't choose the best subject title.  My question was about insecure wireless networks; not insecure websites. If you're connecting to an insecure wireless network, is there anyway to determine rather or not the administrator of that network is watching what you do on the computer? My question is actually pertaining to insecure wireless networks; not insecure websites.  


Also, can you prevent the administrator from watching you?

You should assume you are being watched...Period.

I agree with Patio, also you should note that connecting to an unsecured network also means (especially with Vista and Windows 7) they could easily detect your machine and do some nasty things given the chance.
