hi, i formated my Pc 2 days ago and installed win xp sp3. then i noticed that the "Folder Option" not in tool menu and i can't open task manager too, so i searched in google to know how to slove it and i found the answer that i open "RegEditor" and delete "NoFolderOption" key in the path " HKEY_CURRENT_USER\Software \Microsoft\Windows\CurrentVersion\Policies\Explorer " but i couldn't open the RegEditor because when i want to open it, it opens with notepad. i tried to delete this key with tune-up regeditor but it keeps come back. my finally move that i installed avast antivirus it works and delete all the warms but now i still havn't "FolderOption" in tool menu , and i can't open RegEditor or Computer Managment i keep have a message box "windows can't access to the specified device,path or file. you may havn't the appropriate permissions to access them" what can i do???? thanks all adavnced 1 person needs an answerI do too

You apparently either didn't really do a clean install of Windows or you infected your computer again immediately. http://michaelstevenstech.com/cleanxpinstall.html - Clean Install How-To http://www.elephantboycomputers.com/page2.html#Reinstalling_Windows - What you will need on-hand http://www.elephantboycomputers.com/page2.html#Removing_Malware MS-MVP - Elephant Boy Computers - Don't Panic!

First : thanks after i installed avast anti virus, my pc is clean now , but i still have a small problem which is i can't enter registry editor, computer managment, device manager, ...... etc. when i click on them i got a message for example when i want to enter regeditor the message is " windows can't find "regedit". make sure that you typed the name correctly ..........". even if i tried to open it from c:\windows\regedit.exe,i got the same message

Once again, your computer is either not virus/malware-free because you didn't do a clean install (only did a repair install) OR you did a clean install and then immediately reinfected yourself by installing something bad. The behavior you have described is symptomatic of severe infection and does not appear after a clean install of Windows. Do a clean install of Windows and then pay attention to what you are installing afterwards. While Avast is a fine free antivirus, it will not remove all malware. See the link below for how to do thorough malware removal. However, I think you should do a clean install. Make sure you have backed up your data to external media first. Go through these general malware removal steps systematically: http://www.elephantboycomputers.com/page2.html#Removing_Malware Include scanning with David Lipman's Multi_AV and follow instructions to do all scans in Safe Mode. Please see the special Notes regarding using Multi_AV in Vista. http://www.elephantboycomputers.com/page2.html#Multi-AV - instructions http://tinyurl.com/yoeru3 - download link and more instructions When all else fails, get guided help. Choose one of the specialty forums listed at the first link. Register and read its posting FAQ. PLEASE DO NOT POST LOGS IN THE MS FORUMS. If you can't do the work yourself (and there is no shame in admitting this isn't your cup of tea), take the machine to a professional computer repair shop (not your local equivalent of BigComputerStore/GeekSquad). Please be aware that not all local shops are skilled at removing malware and even if they are, your computer may be so infested that Windows will need to be clean-installed. If possible, have all your data backed up before you take the machine into a shopMS-MVP - Elephant Boy Computers - Don't Panic!
