over the last few days my norton keeps popping up warning me of intrusion attempts like the example below im on a single pc (no network) on winxp sp2 so it would seem from norton website that this is not a threat - but it keeps happening. from the ip address it seems to be a nearby number with the same isp as me i cant get any response from my isp (bt) and also notice that my neighbour has the same problem also on bt ive turned off the warnings and the firewall is doing its job - will it stop in the end or should i do more ive run virus scans, updated windows etc thanks Details: Attempted Intrusion "MS ASN1 Integer Overflow TCP" against your machine was detected and blocked.
