Thats this?
Found in c:\winnt\ sandboxed

Wait for the Sandboxie experts, to see if they can identify this file...

In the meantime:
I use V 2.86 of Sandboxie.
I searched my hard drive, and this file is not there.
I also do not have a "C:\Winnt\sandboxed" folder.

A Google search for that filename found only links to a Russian web site where a translation, provided by Google, seems to indicate that this file could be part of a Trojan that collects information from the computer.

They mention Kaspersky anti-virus picking-up on this file, so I would suggest you do a free online virus scan at the Kaspersky web site, to verify that your computer is clear:
http://www.kaspersky.com/virusscanner

The web page states:
"This free online virus scanner is very powerful and scans your machine very deeply, so it could take hours to complete. We suggest running it during a time of low activity"

Really Strange.

SbiePst.dat contains the sandboxed copy of your 'protected storage' data. More info:

(Recently revised.)

Note, if you have Sandboxie set to not sandbox the protected storage ('allow full access to Protected Storage...'), then this file will not be created or used.
