installed Norton Systemworks 2003 with NIS on Nov 2, fully updated it on Nov 4 when it detected "Netspy Trojan Horse" with no recommendation or observed action by Norton. have a history of problems on this machine for 4 months. origin OS Win98 Nov 2001, performance degraded over a period of months, frequent crashes, "bad image" diagol boxes, IE corrupted, finally died. upgraded to XP Professional Mar 2002. discovered 2 months after installing XP the firewall was switched OFF. i was later informed the firewall is operational upon installation without requiring to be manually turned on. is this is true? The same installer reinstalled XP with SP1, Oct 2002, informing me there were now no viruses/trojans after making changes to the registry and turned the firewall on. Thinking things were not as they should be had a new XP installed by a new installer Nov 2. he generated a new key and ran SP1. machine crashed the next day wiping out large volumes of Windows system files. he fixed the problem then loaded NIS which then detected Netspy. currently, Norton terminates and is disabled about once a day, enabling only on reboot. Began researching/learning about security and downloaded Trojanhunter which reports no Trojans, now looking at TDS. I’d very much appreciate any comments. Thank you.
