someone was having a similar problem with Win7 and Virtualbox 3.2.8 in 2010.

the answer appears to be found by going to C:\USERS\<username>\AppData\Local\VirtualStore\Program Files
and then rmdir /s Oracle

the contents there are created by running Virtualbox without Administrator privilege and can safely be deleted.
the new version of Virtualbox will create new files there, if needed.
