SWDoctor.exe creates the insidious and widespread Perflib_perfdata_1c.dat file. The numbers and letter before.dat change. The Pef lb_ Perfcata _ xxx.dat affects MS Word 2003 when you click on an MS Word 2003 .doc file. You cannot delete thr Perflib_ Pefdata _xxx.dat file unless you find tthe application that is creating it. After labourious working on the Peflib_ Pefdata__xxx.dat problem I discoverd that SWDoctor.exe causes it. Uncheck SWDoctor in Run\Msconfig
