imageHere’s a KB we just published that talks about a condition where the status displayed in the FCS Malware Summary report may be a little bit confusing:

=====

Symptoms

When a Microsoft Application Virtualization (App-V) administrator attempts to delete an old App-V package on an App-V 4.5 SP2 Management server, the operation fails with the following error:
Unexpected error occurred.

Unable to delete the specified application. Please report the following error code to your system administrator.
Error code: 0000B005.

Cause

This can occur if the Application_Usage table is too large (e.g. has millions of rows) and there is an Application record in the Application_Usage table associated to the Application ID of the App-V Package that is being deleted.

Resolution

To resolve this issue, truncate the Application_Usage table or delete the specific Application ID records from the Application_Usage table for the application you wish to delete.
First, check the Message_Log and Application_usage tables to determine if they are too large (have millions of rows). To do this, cut and paste the following script into a SQL query window focused on the AppVirt DB:

select count(*) from MESSAGE_LOG
go
select count(*) from APPLICATION_USAGE
go

If millions of rows are found in either table, backup the App-V database and truncate the tables using the following SQL script focused on the App-V Database. Please be aware that this will remove all data from both tables.

truncate table MESSAGE_LOG
go

truncate table APPLICATION_USAGE
go
