good example 3APA3A to teach those software companies
howto, 

anyways... here is a archive, 

http://www.geocities.com/visitbipin/antiPOC.zip

Extract the archive by using "DEFAULT ZIP MANAGER" of
windows xp. It will create a file "NULL.con" (O;
within which there is a "eicar test string file". 

I don't think your super AV will detect the "eicar
test string file" withing "NULL.con" folder??? :)

anyways... let me know HOW? when you figure out to how
to delete "NULL.con" directory.

 You  can  add Kaspersky 4.5x to the list of products
