No, he means FROM: instead of the standard From:
It's very typical for several viruses to use FROM:, TO: and SUBJECT: If 
you look at those messages, it's the first thing that stands out. I've 
never seen that in any other messages, although there may be a few clients 
which do this. But it certainly is a good virus sign if you don't use a 
virus scanner or want to flag these messages as spam, anyway.
