Probably you have resolved this problem on your own already but ... While googling I've noticed in search results one of URLs looking surprisingly similar to URLs you have posted. It was itb.addr.com/cgi-bin/nph-proxy.cgi/111110A/http/www.game-exe.ru/ . I did quick search for nph-proxy which lead me to this website: http://www.jmarshall.com/tools/cgiproxy/.

I guess somebody installed this CGI proxy on your server and is using it for anonymous surfing.
