I am trying to find out what is generating a log file named C:\SQL.LOG. The file has grown to 4 gigabytes in size. The contents of the file look like this:

That is an ODBC log. See KB274551 How To Generate an ODBC Trace with ODBC Data Source Administrator.
Long story short check
HKEY_CURRENT_USER\Software\ODBC\ODBC.ini\ODBCand change the keyTracefrom 1 to 0.
