The error showed up after I removed a trojan from my laptop using Norton 360. The laptop continues to run normally after the error message, but I wanted to know what this error was anyway.


Error loading c:\progra~2\yagowifu\yagowifu.dll

The specified module could not be found.

    That's the system still trying to launch the virus even though the file has gone.
    Go to and launch autoruns.exe
    Press escape to stop it scanning, then select Options - "Hide Microsoft and Windows Entries" and then press F5 to rescan.
    Now look through the list for the entry referencing that file.  Untick it.  Then press F5 and scan again to check that it does not come back (or another similar one).

    If you have any doubts over the cleanliness of your system, use a 2nd scanner such as

    I'm with cantoris, that definitely is the cause for the error, use msconfig to deselect the "bad one'. Or even better yet, use Revo uninstaller (freeware) under windows tools to remove (not only deselect) it.

    I had initially started writing the above using msconfig, except I prefer AutoRuns as it's a good way to spot if the thing jumps straight back in again if there's a dodgy process watching over it.  :)

    Using Revo uninstaller will prevent the thing from jumping straight back in again even if there's a dodgy process watching over it.

    1. Open Msconfig - Select "Hide all Microsoft services & startups" under genaral tab and click OK.
    2. Select Exit without restart.
    3. Open Registry Editor, Go to HKLM\Software\Microsoft\SharedTools\MSCONFIG\Startups and on the right pane, look for the startup item with the file name or path name - c:\progra~2\yagowifu\yagowifu.dll
    4. Delete the file from the registry.
    5. Open MSconfig - Deselect "Hide all Microsoft services & startups" under genaral tab and Click OK.
    6. Restart the machine. Check for error messages.

    All the best!!!
