Does Norton say where those 15 infected files are located? We need to delete them.
This is what I can find from that
trojan name you gave us. If you intend to edit the registry, make sure you back it up first (File->Export Registry and save it somewhere).
It may be easier if you try running this program and see if it will catch those trojans for you:
Let's use a program to scan for any trojans that may exist. Download
TDS-3. Learn how to use it
here. Make sure to update it after you installed it. You can get the manual updates
here. When you launch the program, it will scan your memory for running processes. This will take less than 30 seconds. Next go to
System Testing on the menu and choose
Full System Scan. After that's finished, post the log file by selecting everything on the top pane (select from bottom to top). If any alarms are found, it will be listed in the bottom window. Please copy and paste that here also if it applies.
