Hadn't ran the Avast linux edition in a while,
but it found a Nutcracker type virus in some
old iso's that never got burned to disk:

PCBSD and Ecopup.

These had to be deleted manually through the file manager, Avast
wouldn't do it. It seemed to flag 2 other files the home directory
(.dbus and another associated with dragonfly bsd, but similar
look with the ".") Those I was able to put into the chest.

Full shutdown and booting a couple minutes later no longer
shows anything coming up after doing a full system scan,
so hopefully it never affected the system.

Basic Nutcracker info from McAfee:
