I have all the Norton 2005 products installed, what file is it exactly thats causing you the problems, i'll have a look on mine and see if i can see anything. When i first installed 2005 GoBack it messed up, but restarted and did it again and all worked out okay. I've had in installed since oct. 2004 and no problems as of yet. One thing did strike me as strange though, i got a high risk alert for Welchia_ISMP_Scan attack. only thing is, it came from my IP, and was blocked, normally when things come from my IP its just a new program that i havent run for a while which needs norton configuration requests and such, but I was online as usual, and my net transfer activity started going crazy (64k isdn so it's easy to tell) and then a few minutes later i got that. ran all relevant system checks NAV Ad-aware etc, just cleaned up my machine, no virus though.
I've yet to hear about any 2005 global problems, how long have you had yours installed? Oh, and after mine didnt install first time i used the msconfig technique describe previously to allow me to uninstall fully as when windows is booted with partial/full install the processes can't be terminated.
