When you select either 'Disinfect' or 'Delete' from the SBAV CD menu when your computer was not shut down properly, the following prompt will appear:
The disk is marked 'in use'. Probably Windows was not shut down correctly. Your options are:

Proceed with the scan at your own risk. This may result in disk corruption. If in doubt, contact Sophos Technical Support.

If you have tried shutting down Windows from the Start menu without success, please contact Sophos Technical Support.
If you proceed with the scan on an NTFS hard disk that was not shut down properly:

once the scan is complete, you should perform a Windows Disk Integrity check on the computer as soon as possible to repair any damage.
