Norton Anti Virus 2011

When my subscription was due I downloaded Anti Virus 2011 free. It is working fine but although set to scan incoming and outgoing emails the scan progress is not shown in the task bar and the emails are downloaded much faster than with 2010 - almost as if they are not being scanned.    Is this a feature of 2011 or is something not working properly?  I do like to see the progress of scanning - makes me feel so much safer  <G>
