Norton Internet Security keeps flashing a warning that I am under attack from Netspy Trojan. This can occur when I am not on-line (Broadband). The computer address is 127.0.0.1 and belongs to my local network - but I have no network, just me. Having traced these details Norton Internet Security is happy, stops warning me and does nothing until the next time I boot up, when I might get a warning signal again, or not. I've searched using Spybot but nothing is found. All very odd. Any ideas ?
