Binary package hint: software-center

Description: Ubuntu Natty (development branch)
Release: 11.04

I was in the Ubuntu Software Centre searching for an anti virus program and the software centre crashed.
This is a fresh upgrade from 10.10 and I did have ClamAV installed before, when I was checking through my applications I noticed I had no anti virus.
