Hello

My desktop has been acting up for a while with various "anti-spyware" programs installing themselves on it. Then one day my keyboard stopped working, and I realized that somehow the driver had become corrupted. I tried purchasing a wireless keyboard with software but that doesn't work either. Is there anyway I can get a keyboard to work on it?
Thanks for your help in advance.

Will the keyboard work in safe mode? Does your mouse work okay? We can try the onscreen keyboard. Let's try a procedure using safe mode:

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.

Is it possible to downloard Super Antispyware onto another computer and put it on another computer using a disc or flashdrive?

Also it's showing that it can't find any driver for just the standard keyboard that came with it.

Yes, you can download and transfer.

Have you tried the keyboard in safe mode?

Are you seeing a "code 39" keyboard error in Device Manager?

Rigel:Well, I tried loading the computer in safe mode, and the keyboard allowed me to use the enter and arrow keys. However, after selecting the safe mode option the computer tried to boot up but then keeps trying to boot up again and again. It seems to boot up okay in normal mode however an error message pops up that says "Error Loading C:\WINDOWS\system32\nlgyldpy.dll Specified module could not be found.

AustrAlien: Whenever I check the drive for the keyboard that came with the computer nothing shows up for the driver. When I try to check the driver for the wireless logitech keyboard I installed yes it does show code 39 error.

You could probably get by with the on-screen keyboard
Start > Programs > Accessories > Accessibility > On-Screen Keyboard
............ but it would be so much easier if your keyboard was actually working.
Let's have a quick look in the registry to check out one possible cause for the keyboard(s) not working ....

WARNING:
(The information provided requires using the Windows Registry Editor.)
Improper changes to the registry could render your computer inoperable.
Do NOT make any changes while using the Registry Editor to obtain the necessary information.
********************************************************

Start > Run > and type "regedit" and press <ENTER>
Navigate to the following key, in the left window pane ...

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318} <<< key

and highlight it (left-click on it). *Be sure to locate the correct key.
Now, in the right-hand-side window pane, you will see on the left under "Name", "UpperFilters".
Double-click on "UpperFilters" and a small window will open.
Please record the items you see listed in the window under "Value data".

Now click "Cancel" to close the small window.
Now, close the Registry Editor window.

Please post the list of "the items you see listed in the window under "Value data"".

(SSKBFD) Webroot Spy Sweeper Keylogger Shield Keyboard Filter
Perhaps you have un-installed Spy Sweeper? What-ever change has occurred .... you now need to remove the entry "SSKBFD" from the Value data list, after which your keyboard will function.

WARNING:
(The information provided requires editing the Windows registry.)
Improper changes to the registry could render your computer inoperable.
The following instructions include steps to save a back-up copy of the relevant part of the registry before making any changes.
Do not neglect to make those back-up copies.
********************************************************

Start > Run > and type "regedit" and press <ENTER>
Navigate to the following key, in the left window pane ...

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318} <<< key

and highlight it (left-click on it). *Be sure to locate the correct key.
Now, right-click on that key, and choose "Export".
Choose a location, and give the backup file a name "SSKBFD", and click on "Save".

Now, in the right-hand-side window pane, you will see on the left under "Name", "UpperFilters".
Double-click on "UpperFilters" and a small window will open.
Remove the entry "SSKBFD" from the Value data list. Click "OK" to close the small window.
Now, close the Registry Editor window.

Go to Device Manager
Right-click on "My Computer" > "Properties" > "Hardware" > "Device Manager"
and expand the "Keyboards" entry.
Right-click > "Uninstall" any entries that you see for your keyboard(s).
Then on the Main Menu > Action > "Scan for hardware changes"
and the driver for your keyboard should be installed.

You may or may not need to re-start your computer? Your keyboard should now be working.
