buteman, yes, I also googled it and found nothing as well! Strange. It must belong to something though?
Sea Urchin, the error is a 'standard' sort of notification box that pops up as soon as the desktop has loaded, with the blue band at the top and the word RUNDLL in the blue band, the message inside the box is as I typed it:
Error loading sijw.fko
The specified modlue could not be found
I will do another malwarebytes scan in safe mode then see what happens.
