Good advice Jerry...NCSA studies suggest winword.concept has become the most
widespread virus and got to that point faster than any previous virus.
Here's a good quote from a Microsoft project manager last February "At
Microsoft We scan every server every day [for the winword.concept virus] and
we are still getting infected."
Fast forward to August, and Spencer F. Katt reports that Msoft Internet czar
Brad Silverberg sent out to his troops, as an email attachment, a Word doc
describing the benefits of Internet Explorer 3.0, infected with winword.concept.
I have caught flak myself for saying "winword.concept does not destroy
data." Of course, I mean that destroying data is not part of the payload,
but I have heard from quite a few people who have had large documents so
screwed up by infection and attempted disinfection, that they have indeed
lost data.
