Did I get hacked?

The entire contents of my /home/grant/vmware folder have suddenly
disappeared.  I haven't noticed anything else strange yet.  I did
configure and start shorewall for the first time yesterday instead of
using a few iptables commands from the Gentoo Home Router Guide, and
I'm running PenguinTV (a video RSS aggregator with an ebuild in
bugs.gentoo.org) and transmission (a bittorrent client in portage) for
the first time.  My shorewall config is here:

What should I do next?
