Avast 4.6.443 generates errors when receiving performance report

Hi,

I receive a lot of error messages when SBS2003 server is sending a daily performance report which is generated after the server is rebooted:

2304 Entry point _cftFreeLibrary@0 not found in module C:\Program Files\Alwil Software\Avast4\aswEnhcd.exe.
2304 ODBC function SQLFetch() - GetColumnProp failed. Error description: .

What cause these errors?
