I have read of some success removing this error message using SDFix. It seems it is a leftover from a previous infection.
Download SDFix and double click the exe file. This will create a text file.
Reboot into safe mode and open the text file.
The text file will display where SDFix was extracted to.
Copy the path into the run box and click ok.
Double click the RunThis.bat file.
Follow the prompts.
