A common technique that spyware, adwares, viruses, keyloggers etc use to hide from users is to drop files on the system that use the same name as a legitimate file but in a different folder. WinDir.spoolsv is a warning that there is a file named spoolsv.exe located in %WinDir% on your system. The legitimate spoolsv.exe file is located in %SystemDir%. You might want to analyse %WinDir%\spoolsv.exe to verify it is something that you really want on your system. Do not delete %WinDir%\spoolsv.exe unless you are 100% sure it is a threats.

Note: %WinDir% is a variable (?). By default, this is C:\Windows (Windows 95/98/Me/XP) or C:\WINNT (Windows NT/2000).
Note: %SystemDir% is a variable (?). By default, this is C:\Windows\System (Windows 95/98/Me), C:\WINNT\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
