I guess malware. How to find which file

For almost 10 years I have been using `Naviscope' as my filtering (& many
more) localhost proxy software for net surfing. Yesterday I came to know
(thru Naviscope's Resource bars) that some trojan or malware, I suppose,
trying to connect to www.google-analytics.com. Immediately I took the url
copy paste of the link which is pasted below.

http://www.google-analytics.com:80/_...3D(none)%3B%2B


How to know which file/program is trying to connect to this site through
Naviscope. Tcpview did not help in this regard.
I am running XP Pro sp2, Avast AV/Comodo Firewall/Adaware with latest
definition nothing
found.

Thanks for all the replies
