Mini treasures and Norton

I heard that Norton was complaining about the Mini treasures wiki, here is the warning:

Viruses
Threats found: 1
The complete list:
Name of the treat: W97M.Thus.A
Location: litchickmccain.pbworks.com/f/AP+2008-09+syllabus.doc

Of course I got scared when I heard this but

• there are no *.docs in my wiki
• the location is referring to another wiki (called litchickmccain). There are no links to that wiki from my wiki and the only common thing we have is the platform (PBworks).
  

So I am saying that it is very safe to use my wiki. But tell me if you got more warnings about it.
