Office / Business

So I have a few users setup with daily backups using a bat file as referenced in
http://www.ctunion.com/node/35

So I noticed not all the user’s data was being copied, only half the data was being copied. So I ran the command from the bat file in a dos prompt:

xcopy "c:\Documents and Settings\user\My Documents" "d:\backup" /e /c /y /d

and it is setup to copy only files that have been modified with /d switch
I noticed after it copied some files that have changed it gave an "insufficient memory" error

I ran the same command again and it copied no files and returned the "insufficient memory" error again.

What is SPR/Rootkit.XCP.B.5? When i ran AntiVir virus software it brought up SPR/Rootkit.XCP.B.5 and deleted it. I searched the net to find out more but i couldn't find anything. Since then I downloaded UnHackMe software to search for hidden trojans but it hasn't found anything since.
Does anyone know?
