Hi LittleFrank
Can you confirm you have Administrator access on your pc,
If no antispy scanner can remove the entry and you cannot
remove the entry manually after checking Full Control
then it sounds like you are logged into a limited
account.
Try going to Start Menu and control Panel then to User
Accounts, Create a new Admin account and try deleting the
key using that.
If you are sure you are dojng this from the Admin account
then try it this way :
download and install Registrar Lite.
http://www.resplendence.com/download/reglite.exe
Run reglite and paste this line into the address box:
HKEY_LOCAL_MACHINE\SOFTWARE\ISTbar.
Click on 'Go', then highlight ISTbar(reglite will have
already selected the key) in the left pane,
right click it and select 'Delete'. If you can't delete
it, Highlight the key and from the Security menu on the
top bar press "Take Ownership" and try to delete the key
if this doesnt work try "Edit Permissions"
under 'Security' from the same pull down menu at the top
(with the key still highlighted). Make sure 'Read'
and 'Full Control' are selected for your account(in the
top pane), click 'Ok' and try to delete it again.
If this doesnt work then save this regfile, Open Notepad
and copy & paste this into it:
REGEDIT4
[-HKEY_LOCAL_MACHINE\SOFTWARE\ISTbar]
Save as Type "All Files" and call it fix.reg
save it to your desktop
download Ewido Security Suite and update it in normal
mode and run it in safe mode (Reboot and keep tapping F8
then choose safe mode from the list)

After unning Ewido Use the Regfix you just saved and
double click it and allow it to be merged into the
registry, reboot and check that it has been removed.
If this doesnt work then download the FindItNT-2K-XP.zip
http://castlecops.com/zx/Zupe/Find It NT-2K-XP.zip
extract the files from the zip. Navigate to the Find It
NT-2K-XP folder and double-click on find.bat. A command
prompt will open and it will search your computer for
malicious files. Once it has finished a Notepad window
will pop up with output.txt. Copy the entire contents of
output.txt into your next post.
