old defs stick around sometime - NAV 2009

Hi,

 

Running NAV 2009 - all seems fine - updates frequent

 

However, normally after a full update I have one set of definitions in the VirDefs folder called something like 20081030.003

 

Occasionally there is still an old set sat in the folder, when this happens I see a reference to APP_ID_AVORPHAN in usage.dat

 

Here is the conents of that file

 

[20081028.024]
APP_ID_AVORPHAN_1=1
[20081030.003]
APP_ID_AVORPHAN_0=1
APP_ID_SCANNERW=1
SRTSP=1
AVDEFMGR=1

 

Where 20081028.024 is the old def folder still in the virusdefs folder

 

Anyone able to explain what is happening ?

 

Thank You
