3 files from C:\windows\system32 cannot be cleaned or deleted, not even in safe mode, can someone please give me a clue how to get rid of them. They are: imapi.exe, mstsc.exe, dvdupgrd.exe. win32/virut.nbp virus These files just keep coming back System restore in disabled on both hard drives I also had files from servicepackunistall and servicepack\i386 with exe files coming up as win32/virut.nbm virus. hopefully I have been been able to clean these and have no more worries with them. Thanks. Zigi.
