Has their been a change to the unpacking of Virus Defs?

Hi,

In our environment we've recently noticed that when the definitions expand out it's creating a folder of approx 900Mb that Symantec does nothing with. After about 30 mins it then expands out again with a new folder and successfully updates to the correct definiton.

Due to the nature of our environment we have limited disk space, due to this we have noticed the change in the expanding as it fills the disk.

We have looked through the logs and can find no errors or entries regarding the first expansion that Symantec does nothing with. The only thing we can think is that the unpacking of the definition files on the drive has changed recently.

Thanks
