I've experienced the same problem. It started on 7/3 when I booted up my XP
machine and went to log into my profile. I got a dialog box message
that the profile lacked required priveleges and the system rebooted in
30 seconds. The other profiles did not behave the same way. I spent
an hour re-creating my profile and moving email, documents, etc. Ran
ad-aware and hijack, found traces of the IMISERV virus (including a
suspicious wupdt.exe executable), kept at it until an accompanying
browser hijack disappeared.. (all this on a machine with current nav
definitions, behind a firewall, latest patches, and strong password
security... and a daughter of course, just like the commercial).
The machine seems clean. No sign of any suspicious activity. However,
the quick launch feature is dead. I can check off the option under
toolbar properties, but the setting does not stick, and the quick
launch bar does not appear. The folder is present in the profile, it
just doesn't do anything.
