Getting rid of the IST Bar was certainly a JOB!! Numerous
runs of Spybot Search and Destroy, along with Ad-Aware.
While both of those programs detected the IST... and I
removed the entries found, they didn't find all
occurrences of the malware. Finally, feeling frustrated
and with nothing to lose, I bravely and naively
entered "regedit" without a backup no less!! Once in the
registsry, I promptly hit "Find" - ist... and deleted
every entry manually - and there were plenty (not to
mention I had to be aware and not delete hISTory, for
example). I haven't had the IST problem since - and,
luckily didn't detroy winXP in the process of editing my
registry (which I know little about!). By the way, I
rather like MS AntiSpyware, it is really very very fast,
and combines the actions of spybot and ad-aware, it seems
to me. I know that MS AntiSpyware caught a browser
hijack immediately... ran a scan and detected 7 problems.
McAfee virus scanner was also running at the time - it
was a bit slower in catching the hijacker, the scan took
at least 3 times as long, and it only showed 1 problem
(and, no I had not yet deleted the errors MS AS had
detected because I wanted to see how each program did
their job!). (sorry - longwinded tonight). *smile*
