|Sump.exe is part of Uniblue speedup, so your error message iis all down to that program.|
If you can't uninstall it then try it in Safe Mode. Otherwise type msconfig in the Run box and if it is present in startup then you can at least disable it while you sort out the mess.
I agree, avoid aa magic speedup or cleanup programs you see on the net. Even when they are not scams they screw up your computer.
Always pop back and let us know the outcome - thanks
