I'm using W7 and it works very well.
Your problem may come from gameranger that can't get your IP or can't send it to AOM.
Have you tryed to uninstall both aom and GR, delete remaining folders in program files and mydocs/my games, disable completely kapersky and reinstall AOM and then Gameranger?
Then, check your network center (in control panel). Your network must be Private network and not public (neither office)
If you can, forward UDP16000 port to your computer (in your router)
Try to host without enabling kapersky, or be sure that kapersky firewall allows both AOM and Gameranger
The best defence is attack!
