FreeBSD 7.0 hanging up randomly - again

[lumiwa]

Hi!

As it described in the topic "FreeBSD 7.0 hanging up randomly" I found my computer in the "freezing" mode again but I found also in the user .history file:

cd "`printf "%b" '\0057'`"

I did check logs (auth, pflog...) and there are nothing.

Thanks in advance.
