I have a server that creates multiple "at****" tasks every hour.
From event viewer:
Task Compatibility module failed to update task "At453.job" to the required status 4. Additional Data: Error Value: 2147942402.
We have Sophos antivirus running on the server and is up to date.
We have run the antiroot kits on the workstations and server.
Forgot to mention it is running Windows Small Business Server 2011
