Double Click on "AppInit_DLLs" located in

2) Rename the hidden file:
Close Windows and reboot using "Windows Recovery Console". Browse to the system32 directory located at: C:\Windows\system32\. Replace this path with your system32 directory. In order to know your system32 run cmd and type:
echo %WINDIR%\System32

After finding your system32 directory do the following:
a) Change file from read only by typing attrib -r hidden.dll
b) Rename the file (For some reason this only works after rename) type: rename hidden.dll nasty.dll (and remember that "hidden.dll" is for this explanation only use the name you found earlier)
c) Type "exit" and reboot to Windows.

3) Edit registry to remove hidden file:
Run "reglite.exe" again.
Double Click on "AppInit_DLLs" located in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\\. Delete the file in "value" window, the "size" window changes also. "Apply" changes and exit "reglite.exe"

Check the boxes to remove the following entries:
