Virus: Remarks about Virus Volume reduction since mid-decemeber 2006

Hi,

    We had a constant volume of virus trapped by clamav, mcafee, etc. of about 2% of all mail traffics coming from outside our network.

    Since mid-december the volume is now under 0.2% while the mail traffic stay in line with the tendencies of the previous year.

    I'm not looking for opertional instructions about clamav, broken config, etc. But if anybody else noticed a volume reduction also?

    And I'm curious to find out which network finally got fixed...

    Thanks and have a good year.
