For the sybfilter driver to work properly, the Microsoft Filter Manager Library must be version 5.1.2600.2978 or later. To determine the version of the library, right-click c:\windows\system32\fltlib.dll in Windows Explorer, select Properties, and click the Version tab in the Properties dialog. If the version is earlier than 5.1.2600.2978, go to the Microsoft Web sitehttp://windowsupdate.microsoft.com, and update your Windows system.
