Hi Cyril,

Are they trojans or viruses? By combining the names, you are
pretending that two entirely different things are the same. A trojan
is not a virus, and vice versa. Most antivirus programs take only
passing notice of trojans.
Since your daughter's computer apparently already has Norton AV
installed, you should update it and let it attempt to repeir also. If
it has expired or the LiveUpdate won't work for some other reason,
then all you have to do is go to
http://securityresponse.symantec.com/avcenter/download.html, download
the latest definitions, set the system date back a year or two to a
time before Norton expired, install the update (the update will not
install unless the date is prior to the exiration date), then restore
the date to the correct value. Once you have it updated, you can then
do a full scan of the system again with Norton.
Since you don't know what other kinds of junk is on her system, you
should attack with other programs as well. Start with AdAware and
Spybot Search & Destroy (BOTH of them, not just one):

I'll conclude with a quote from one of Ekhart's messages:
