If you have tried to stop some of the Trend Micro Services before and found that the stop option is greyed out like below, you might be concerned that things are not right with your server. In fact – they are very right indeed. I normally recommend stopping all Antivirus Services before installing major updates like service packs for Windows or Exchange Server and so on.
Trend Micro WFBS has a feature to increase the security on it’s services so that not even an administrator can stop them. This feature is designed to help prevent malicious programs from terminating Trends ability to protect your system from infection.
In order to disable this feature temporarily, you need to login to the WFBS Security Server console, navigate to the Security Settings for that group – this is my server so it’s in the Servers (Default) group.
You will see in the screen shot below, the Client Security setting is set to High. Change this to Normal and select Save.
Now – on the Server computer itself, right click on the Trend CSA icon in the taskbar and select Update Now. Give it a minute to grab the latest configuration from the Trend Security Server and then you will be able to right stop services again. See below.
Make sure that after you have done your maintenance, that you go back into the Trend Security Server Console and change the setting back to High.
