automatically update kaspersky from command line

hi ho =)

im running a very low-end machine and dont want to keep
kaspersky avp controll center (which does the automatic
(daily in my case) update).

i know (needed to open the ports for my firewall) that it
is done by the file "avpupd.exe"

now when i run it manually, i only get some gui which
finally leads to the update, but _not_ automatically.

so what parameter will i have to use the feature as id
like to?

thx in advance
