i had been doing lattly a search and what i am looking for is aprogram that can protect the dll files in the system32 folder or windows folders from deleting or damaging or anything else cuz sometimes when i restart the windows and the loggin winxp shows up it just threw me to the checkdisk and begins checking,after finshing and restarting and when entering the windows it just pop up an error message, let me give you an example:
winlogon.exe cant load cuz didnt find the file (sfc_os.dll) and you should reinstall the program....... somthing like that i dont remember the exact words but i fixed it without reinstall.
so what i am afraid of that some day it will do the checkdisk and delete afile that worse then the example that i minshined.
