How To Enable Folder Options in Windows Explorer

Malware often drops itself as a hidden file and then disables the Folder Options menu in Windows Explorer so you can't change the settings to view hidden files and folders. If you are unable to access the Tools | Folder Options in Windows Explorer, here's how to modify the registry to regain access to the Folder Options menu.


  1. Click Start
  2. Click Run
  3. Type REGEDIT
  4. Click OK
    The Registry Editor will now open
  5. Browse to the following key:
    Note: HKCU stands for HKEY_CURRENT_USER
  6. In the right pane, look for the value: NoFolderOptions
  7. Right click NoFolderOptions and select Delete. (When prompted with "Are you sure you want to delete this value", select Yes.
  8. Now browse to the following key:
    Note: HKLM stands for HKEY_LOCAL_MACHINE
  9. In the right pane, look for the value: NoFolderOptions
  10. Right click NoFolderOptions and select Delete. (When prompted with "Are you sure you want to delete this value", select Yes.
  11. Close the Registry by choosing File | Exit
  12. You should now be able to access the Folder Options menu. If not, reboot into Safe Mode and repeat the steps outlined above.

How to remove new folder exe or regsvr exe or autorun inf virus

I want to tell you a story, two days back i got affected by this virus very badly as it eat up all my empty hard disk space of around 700 MB :( .

I was surprised that my most reliable friend Avast, for the first time failed me in this war against viruses but then again avg and bitdiffender also failed against it. This virus is know popularly as regsvr.exe virus, or as new folder.exe virus and most people identify this one by seeing autorun.inf file on their pen drives, But trend micro identified it as WORM_DELF.FKZ. It is spreading mostly using pen drives as the medium.

New folder.exe virus

Well, so here is the story of how i was able to kill the monster and reclaim my hard disk space.

Manual Process of removal

I prefer manual process simply because it gives me option to learn new things in the process.

So let’s start the process off reclaiming the turf that virus took over from us.

  1. Cut The Supply Line
    1. Search for autorun.inf file. It is a read only file so you will have to change it to normal by right clicking the file , selecting the properties and un-check the read only option
    2. Open the file in notepad and delete everything and save the file.
    3. Now change the file status back to read only mode so that the virus could not get access again.
    4. Autorun INF: cutting the supply line
    5. Click start->run and type msconfig and click ok
    6. Go to startup tab look for regsvr and uncheck the option click OK.
    7. Click on Exit without Restart, cause there are still few things we need to do before we can restart the PC.
    8. Now go to control panel -> scheduled tasks, and delete the At1 task listed their.
  2. Open The Gates Of Castle
    1. Click on start -> run and type gpedit.msc and click Ok.
    2. Opening the gate of castle: starting the gepedit or msconfig
    3. If you are Windows XP Home Edition user you might not have gpedit.msc in that case download and install it from Windows XP Home Edition: gpedit.msc and then follow these steps.
    4. Go to users configuration->Administrative templates->system
    5. Find “prevent access to registry editing tools” and change the option to disable.
    6. Opening the gate of castle: Group Edit Policies
    7. Once you do this you have registry access back.
  3. Launch The Attack At Heart Of Castle
    1. Click on start->run and type regedit and click ok
    2. Go to edit->find and start the search for regsvr.exe,
    3. Launch the attack in the heart of castle: registry search
    4. Delete all the occurrence of regsvr.exe; remember to take a backup before deleting. KEEP IN MIND regsvr32.exe is not to be deleted. Delete regsvr.exe occurrences only.
    5. At one ore two places you will find it after explorer.exe in theses cases only delete the regsvr.exe part and not the whole part. E.g. Shell = “Explorer.exe regsvr.exe” the just delete the regsvr.exe and leave the explorer.exe
  4. Seek And Destroy the enemy soldiers, no one should be left behind
    1. Click on start->search->for files and folders.
    2. Their click all files and folders
    3. Type “*.exe” as filename to search for
    4. Click on ‘when was it modified ‘ option and select the specify date option
    5. Type from date as 1/31/2008 and also type To date as 1/31/2008
    6. Seek and destory enemy soldiers: the search option
    7. Now hit search and wait for all the exe’s to show up.
    8. Once search is over select all the exe files and shift+delete the files, caution must be taken so that you don’t delete the legitimate exe file that you have installed on 31st January.
    9. Also selecting lot of files together might make your computer unresponsive so delete them in small bunches.
    10. Also find and delete regsvr.exe, svchost .exe( notice an extra space between the svchost and .exe)
  5. Time For Celebrations
    1. Now do a cold reboot (ie press the reboot button instead) and you are done.

I hope this information helps you win your own battle against this virus. Soon all antivirus programs will be able to automatically detect and clean this virus. Also i hope Avast finds a way to solve this issues.

As a side note i have found a little back dog( winpatrol ) that used to work perfectly on my old system. It was not their in my new PC, I have installed it again , as I want to stay ahead by forever closing the supply line of these virus. You can download it form Winpatrol website.

Argument Topic:

1. "Last year, sales of our Fierce Fighter toy airplane declined sharply, even though the toy had been a top seller for three years. Our customer surveys show that parents are now more worried about youthful violence and are concerned about better education for their children. Therefore, to maintain profits we should discontinue all our action toys and focus exclusively on a new line of educational toys. Several other toy companies have already begun marketing educational toys and report sales increases last year of 200 percent. And since the average family income is growing, sales of new Hyper-Go toys should also increase."

Argument Topic:

1. The following appeared in a memo from a vice president of Alta Manufacturing.

"During the past year, Alta Manufacturing had thirty percent more on-the-job accidents than nearby Panoply Industries, where the work shifts are one hour shorter than ours. Experts believe that a significant contributing factor in many on-the-job accidents is fatigue and sleep deprivation among workers. Therefore, to reduce the number of on-the-job accidents at Alta and thereby increase productivity, we should shorten each of our three work shifts by one hour so that our employees will get adequate amounts of sleep."
