While I am aware that warden and things like it can scan the memory of processes, I don't think they are granted full access to read everything on your system. I believe their are restrictions like the file must actively be reading / writing your processes memory before you can scan it.

There is definitely 0 reason that they should be scanning all of the files on your computer and storing them in some sketchy gibberish registry settings. Who knows what else they are looking at.

This is no different then Sony putting rootkits on their audio CD's in order to "prevent piracy". http://en.wikipedia.org/wiki/Sony_BMG_copy_protection_rootki...
