Go tohttp://technet.microsoft.com/en-us/sysinternals/bb963902.aspx and download, install, and run
Autoruns and click on the Everything Tab. Look for the .dll file in the error message 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.
Malke already made the point about malware - as it is llikely that is the original cause and you need to find and remove it so the problem doesn't return (though these are probably only remnants left behind when your current AV program removed
the malware but didn't do so completely).
I hope this helps.

In the meantime, if the error message is saying that a particular .dll is missing at Startup, here is general information about that:
Chances are high that this is a malware file. Either you uninstalled the malware program or your antivirus/antispyware program did. In any case, a reference was left to the file in Startup. You can remove the reference by managing your Startup.
Manage Startup (Make sure you do the malware scanning first!):
(For Vista/Win7) Start Orb>Search box>type: msconfig and when it appears in the Results box above, right-click and choose "Run as Administrator".
If you are prompted for an administrator password or for a confirmation, type the password, or click Continue. Then see what is on the Startup tab. You don't need to restart immediately, but the next time you do you'll get a dialog saying you've used the Utility.
Usually in Vista/Win7 this will be blocked by Windows Defender and you'll need to allow it to run so you can then tick the box that says in effect, "don't bother me about this again".
