Thanks for the log, will go through it ASAP.
A word on the two files you questioned;
SMIBG....this is a USB driver for downloading from within Napster to portable MP3 players.

And I believe that you mis-read this one ihkcmd
It is actually hkcmd.exe
This is Installed by the Intel 810 and 815 chipset graphic drivers. If you want the Ctrl Alt F12 or similar keypresses to access Intel's customised graphics properties, you need it, otherwise not. Can be disabled via Control Panel -> Display Properties.

So both are legitimate files. However. the SMIBG is one I am somewhat leery about, only because it is associated with napster.

I will go through your log and get back here as soon as I can.
