I am having problems with shutdown on a clients computer running Windows XP Pro. The run32.dll comes up when you try to shut down windows. I have tried running Norton Antivirus in both safe mode and normal mode and I have run Lavasoft Ad-Aware 6.0 and SpyBot Search and Destroy and nothing seems to work. I have deleted the run32.dll file from the Windows directory and expanded a new run32.dll from a XP Pro disk and it worked for 3 shutdowns and now it is going back to the run32.dll problem. Can anyone help me with this problem? Thanks
