    That is a long known issue and was described in more depth several times
    in several ML/news in relation with i.e. http://www.fefe.de/antivirus/42.zip
    
    http://groups.google.com/groups?q=42.zip+antivirus returns 27 (!) 
    threads about this issue...
    
    So IMO this so called "announcement" is really no topic here.
