Yeah pull the network plug first. Then boot up with a knoppix CD to backup your data and/or image the disk, then reload. I'm sure you could do a full audit of the system but reloading is likely much quicker. A word to the wise on the account pcguest, if it was one you created, set the shell to something like /sbin/nologin. That can help to prevent unauthorized ssh access if you happen to leave a password blank. I'll leave the additional suggestions and heckles to others on the lists.
