As I already pointed out (several times), it is not safe to
update files in-place.  The *only* safe update is:

 mkdir bases.new
 cp -p bases/* bases.new
 cd bases.new
 fetch_new_files || exit
 ../kavdaemon -something ../testvirus
 [do something with results etc]
 cd ..
 rm -rf bases.old
 mv bases bases.old
 mv bases.new bases
 /etc/init.d/avpd reload

(the same is true for ANY virusscanner).  This is the ONLY safe
method (and no, Ralf, here we see an example where your variant
breaks).  Well, a script should be written based on the above
template... ;)

 Michael.
