I second the VirusTotal online scanner tool that Rick has linked. It’s a great way to check quite a few different providers all at once. Using it can help you identify false positives.
Here are the scan results of the REALSQLDatabase.dll file from the original post. The file was flagged positive in 4 databases, all the same “threat”. Further research of the threat leads to *a lot* of results about false positives.
