Unable to log off after installing IE7

[Guest]

I tried posting this in the XP discussion and it was suggested to post it
here: I have several users sharing a patch updated xp sp2 pc that worked
fine until
I installed ie 7. After that it frequently, but not every time will not let
users log off or shut down including the administrator. The screen flashes,
but nothing happens and you can continue to use applications as if you never
clicked the log off button. I have tried uninstalling and reinstalling ie 7,
searching through ms knowledge base to no avail. I am not running norton
antivirus. I tried looking at the event viewer, but did not see anything
obvious. I have also tried ending all the non system processes listed in
task mgr except explorer one at a time to isolate a possible problem
application and that did not work. The only way to change users when it
won't log them off is a power button reboot. It may be related to a lot of
internet browsing, but I am not sure as it is not consistent. Sometimes you
can log off and sometimes you cannot. I tried to call Microsoft under their
supposed free support for IE7, but you need to give them a credit card number
first and I was disconnected a couple of times so I gave up.

Run a /thorough/ check for hijackware, including posting your hijackthis log
to an appropriate forum.

When all else fails, HijackThis v1.99.1
(http://aumha.org/downloads/hijackthis.zip) is the preferred tool to use.
It will help you to both identify and remove any hijackware/spyware with
assistance from an expert. **Post your log to

If the procedures look too complex - and there is no shame in admitting this
isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA) computer repair shop.
