use zonealarm... it can be download FREELY from www.zonelabs.com
it's a nuisance program but atleast you'll know what programs are getting out and which ones are getting in...
if you don't like that. there is a second option. remove SHARING capability on your Windows machine.
this can be done by clicking START-SETTINGS-Control Panel- Network
then look for sharing file and printer. remove that. and reboot your PC ...
well... hope it helps..
