This doesn't appear to be life threatening but it's one of those annoying little things. For some reason (and this only started yesterday), whenever I close down my PC - ie clicking Start>Turn Off Computer, I get an annoying pop up box 'End Program - rundll32.exe' and I have to wait until the blue progress bar gets to the end after which, I get the message 'Ending program, please wait ...........' and I get the choice to click either 'End now' or 'Cancel'. If I click 'End now', the PC shuts down and if I click 'Cancel', it just goes back to my desktop. It's really annoying and it's never happened before. Any ideas. Help much appreciated.
