The last weeks I noticed that standard Windows XP prgrams are not running anymore, like ipconfig.exe, Remove Hardware (hotplug.dll) and the Windows Picture and Fax Viewer (shimgvw.dll) . The message windows is giving is:
Error loading hotplug.dll The system cannot find the file specified.
Well: this file is present in windows/system32
Disabling the virusscanner solves this problem.
I think this is a serious issue with the Bitdefender program.
Maybe there are more programs behaving like the ones I mentioned.
Putting ipconfig.exe in the exceptions list solves the problem also, but thisi is not the way to go !!!
