Hi, i am new in this site, i think it's very cool!
this is my problem:
Norton found Trojan.Byte.Verify...it said "Deleted", and
Trojan Horse,Download.Trojan - " Not Repaired" - "Access Denied",
is it true? or there might be others...
i found a strange file, msxmidi.exe, that i deleted immediately, and
i ran Spyboot, that found nothing.
But my network does not function anymore.
I have now installed Zone Alarm, i find it's a bit difficult to use.
Can you help me?
Thanks you very much for your help.

I see no other problems in your log. Are you still getting the message from Norton?
You also should get service pack 1 for Internet Explorer.

No, Norton has displayed that message only one time.
I hope it is enoughly powerful to stop those and other Trojans effectively...
I will install SP1 for Internet Explorer, but i also want to try other browsers like Mozilla or Opera.
I hope they have not allthis security problems!
Internet seems to me to be like a jungle..
Thank you very much

It's a rough jungle if you are not prepared . I have used Opera for almost a year now. No virus', no hijacks, no trojans, no running adaware & spybot once a week, no on-line virus scans. Got to be happy with that .
Now, if I could just sort out my hardware .
