The computer is virus free, all updates installed, uses usb ADSL modem. Old HDD no software firewall works fine. New HDD whether with or without software firewall generates this message :hotbounce New install on diffrent PC, connected to USB modem, after dissable of modem (but that may be coincidence) and reconnect, this pc also gives this notice. Take PC home and connect to my router, no problem. Can the USB modem be the culprid ?
