Maybe if you got a GPS module built in your computer. Else the best thing you can do is IP-geolocation, which is between 10 and 100 miles exact. And you dont even need a virus for that, skype broadcasts the IPs itself in certain situations.
****** can track you address using your wlan data in certain areas (they mapped them with their street view cars), but I dont think theres a public API for that.
