Hey good news!!!!!!!! I also had the ista bar problen,
BUT I have found a solution to this problem after
spending about 20 hours trying to delete all of the crap
from this adware. I found the istabar removal tool from
Symantic the information that I found is all here I hope
it helps it did me.
Note: Removing this adware component from the system will
likely cause the program that installed it to not
function as intended. The uninstaller generally
identifies the programs that will not work after
uninstallation.

have a digital signature timestamp of 23 November 2004

The removal tool may terminate Internet Explorer and
Windows Explorer. It is recommended that users save their

1. Updating the virus definitions
Symantec Security Response fully tests all the virus
definitions for quality assurance before they are posted
to our servers. There are two ways to obtain the most
recent virus definitions:
Running LiveUpdate, which is the easiest way to obtain
virus definitions: These virus definitions are posted to
the LiveUpdate servers once each week (usually on
Wednesdays), unless there is a major virus outbreak. To
determine whether definitions for this threat are
available by LiveUpdate, refer to the Virus Definitions
(LiveUpdate).
Downloading the definitions using the Intelligent
Updater: The Intelligent Updater virus definitions are
posted on U.S. business days (Monday through Friday). You
should download the definitions from the Symantec
Security Response Web site and manually install them. To
determine whether definitions for this threat are
available by the Intelligent Updater, refer to the Virus
Definitions (Intelligent Updater).
The Intelligent Updater virus definitions are available:
Read "How to update virus definition files using the
Intelligent Updater" for detailed instructions.
2. Restarting the computer in Safe mode
Shut down the computer and turn off the power. Wait for
at least 30 seconds, and then restart the computer in
Safe mode or VGA mode. For instructions, read the
document, "How to start the computer in Safe Mode."
3. Scanning for and deleting the infected files

registry," for instructions.
