Any improvement?
Shortcuts still won't work? Download this
file and unzip it. Double click on the extracted file. That should repair the shortcut association if it was somehow corrupted.
Fix this in HijackThis:

Do you still get the shutdown problems? If so, does the restart option work (does it restart)?
