Thanks for the hint. I also found it, and the freeware shutdown.exe is
visibly better than Window's shutdown.exe. I succeeded in shutting
down and restarted without difficulties. However, it remains a quizz
for me why the PC did not stop in the first time, when I used the
standard shutdown via the buttons and via Windows's shutdown. exe .
BTW, it's queer to have two programs use the same name.
I guess that I shouldn't have any spyware or malware as I regularly
(?) scan my PC with Spysbot 1.3 and AdAware SE, use AVG antivirus and
ZoneAlarm Security suite. But some Netskys pass into the AVG temp
folder as tmp files and when I want to delete them manually they are
already gone (?). But could a netsky be behind the non-shutdown ???
Thanks for the help
