Avast disspears from the accessories menu

Hello,

I just installed Avast! on Ubuntu 10.04 LTS. Updated, then scanned my system. After it finished, I rebooted. The Avast icon disappeared from the accessories menu. Any ideas?

Hallo,
run this script, whis is responsible for menus/desktop entries: /usr/lib/avast4workstation/share/avast/desktop/install-desktop-entries.sh

regards,
pc
