Run DLL, Error Loading

Go tohttp://technet.microsoft.com/en-us/sysinternals/bb963902.aspx and run Autoruns and click on the Everything Tab.  Look for sshnas21.dll and when you find it uncheck the box to stop it from starting at startup.  Check the whole list as there may be more than one entry.  When done, click OK and reboot.   The message should be gone.

If that doesn't work, try a clean boot http://support.microsoft.com/kb/929135.  If the problem goes away then it's just a matter of tracking down the culprit causing the problem.   Follow the procedures in the article.  Once found, delete, remove, deactivate, or uninstall it.  Once done be sure to reset Vista back to normal status as explained in the procedures. If the problem occurs in clean mode then just restore the system to normal status and reboot - this solution is not going to work.

You may be infected with malware. Try to run anti-malware programs (in safe mode with networking ifnecessary). To fix this problem (if it is a problem) download, install, and run the following two programs:http://www.malwarebytes.org/mbam.php andhttp://www.safer-networking.org/en/index.html.  You may also want to try a free trial of Pandasoft (http://www.pandasecurity.com/usa/homeusers/solutions/global-protection/).  Before downloading pandasoft, uninstall whatever anti-virus program you are currently using (because installing and running two at the same time can cause conflicts, freezes, and all sorts of problems).  Once you've uninstalled your current AV program, download, install, update, and scan using Pandasoft.  I think you might be amazed at how much it finds that the other software missed.  Once complete, uninstall pandasoft and re-install your current AV program (unless you decide to switch which I did when I first tried it about 4 years ago).  You may also want to try the new, free Microsoft Security Essentialshttp://www.softpedia.com/progDownload/Microsoft-Security-Essentials-Download-131683.html (with the same caveat that only ONE AV program can be installed and running on your system at any one time).  You may also want to try the free Avira at:http://www.free-av.com/ and Avast at: http://www.avast.com/index.  Reboot after completing all the scans.  You may also want to try the free OneCare athttp://onecare.live.com/site/en-us/default.htm and let it run all the options (except the registry cleaner) because that’s good maintenance (it will take some time to complete but can be done in the background).

I hope this helps.  Please keep me posted.
