Probably a bit OT for this thread...but another great online threat, especially to newbies, is the 'hoax' email. A legitimate looking email encouraging people to delete certain files from their computer because they are 'known' to contain dangerous code. I receive at least 2 or 3 of these a month forwarded from certain of my well-meaning friends and relatives. I have a standard email reply archieved that I send these people along with the Norton site link that lists these various hoaxes. This standard reply also contains info regarding the dangers of opening email attachment.
