Date of last scan problem

Hi,
My date of last scan isn’t working right on Avast 4.8…shows Date of last scan was 7/6/2008 15:44 but since then I’ve run scans…what am I not doing right here?

Thanks

To get the Last Scan field updated, full HDD scan needs to be made. Please see here: http://forum.avast.com/index.php?topic=11290
