wlnotify.dll - Here is the scoop on "Common Dll To Receive Winlogon Notifications".

wlnotify.dll a.k.a. (Common Dll To Receive Winlogon Notifications)

The big questions: What is wlnotify.dll Is it spyware? What does it do? Do I NEED it? How do I get rid of "wlnotify.dll?

- Details
The library file wlnotify.dll, is required by windows and is used to handle WinLogon related events such as LogOn, LogOff etc. Windows will not work if wlnotify.dll is unavailable. However, if you delete it Windows attempts to replace it automatically.

wlnotify.dll is a valid system process and does not appear to be a security risk.

The Process Server database currently registers wlnotify.dll to Microsoft.

Jay says:

This is part of Microsoft Windows but it is often used by nasty programs to alert you with System Tray pop-ups to false "spyware' problems. They try to trick you into downloading more junk.
Run windows system file checker to ensure the file is authentic:
Start - Run - "SFC /scannow"

If you believe you have an still have an infection, don't blame wlnotify.dll because it just does it's job. Find the real issue and FIX IT.
