Avast slows down deleteing of files on a network drive

I am running Avast 4.7 Server Edition on a Windows Server 2003. This server is making nightly backups which involve deleting a file directory on a mapped networked drive (containing ~ 30gigs in a large number of file folders) using the following command.

RMDIR /Q /S “y:\vault_Backup\Vault\B”

Before Avast was installed this took around 1/2 hour. Now it takes 4-5 hours. Any tips on how to safely configure Avast to avoid this slow-down? Any help would be appreciated.

So, y: is a local or remote drive?

It is a remote network drive.

Does the remote server also run avast?

Thanks

The drive is a D-link DNS-323 Network Storage Enclosure.

If I have my info correct, it is running linux. The firmware upgrade release notes mention upgrading Samba. I spent some time browsing the available docs on the d-link site, but haven’t yet found the details on exactly what it is running. I didn’t see any anti-virus software listed in the configuration screens of the device.

Terminating the “Standard Shield” resident scanner on the server seemed to return the deletion process that I mentioned above to its former speed.

Unfortunately, the actual backup process still took over double the time that it used to take.
