I need urgent help! My windows 2003 server has been hacked. When I was
defragmentating my disks some files could not be defragmentated. I
discovered that the reason is because these files is created on a
userprofile called "superwayne$" at this location C:\Documents and
Settings\superwayne$. If I open this address in Explorer, I see folders like
"desktop", "Favorites", "Local Settings", "superwaynes$'s Documents" and so
on. There is alot of hacked software, movies and other stuff in these
folders.
If I open Active Directory Users and Computers, the user "superwaynes$" is
not there. In Server Management/Users I cant find this either. It seems
like the user "superwaynes$" has been created outside my domain or
something. How can I find and delete this user profile (not only the files
in C:\Documents and Settings\superwayne$)? How could this happen, what can I
do prevent this in future? My server has only licensed software (no hacks),
only I got access to it?

Maybe there is no user and Superwayne just used Documents and Settings
folder to create a share. Look at the owner of the files to see who has
created those - you'll get idea what accounts were compromised.

At this stage you can start monitoring Superwayne's activity and perhaps
even catch the guy (or gal) - useful experience but not very rewarding in
most cases. Another alternative is cleaning out your system - most likely it
is infected with a trojan as well.

If I open "C:\Documents and Settings\superwayne$" and look at the owner of
the files it is "Administrator". Does this mean that the "hacker" has used
my administrator account? Is it smart to disable this account and make a
new administrator account (example called "Admin" with a new password)? Is
it ok to delete (from Command / cmd.exe) the folder "C:\Documents and
Settings\superwayne$" with all content?

It is okay to delete the rubbish.
Create a new administrative account; change password for existing, and alert
on every logon attempt using that account.
The danjer is - if you have a trojan that runs as system, the intruder will
be aware f your actions, and control new account as well.

Thank you! One more question: What is the best way to remove trojans? Any
recommended software for this?
