I have a couple of clients that are running McAfee VirusScan Enterprise 8.5i (non-ePO managed) that have made a few customizations to their install. One client has added RAAdmin.exe to the list of exclusions (double click on On Access Scanner > All Processes > Detection tab > client Exclusions button > Add > type c:\raadmin\*). Another client has create a customized scan task.
Whenever McAfee releases a new engine or a hotfix is applied, the client with the exclusions has their exclusions set back to default (just Windows File Protection) and the client that has a customized scan task says that their scan stops working properly. In both cases they have to redo all their settings.
Is this behaviour normal when a new Engine or a Hotfix is applied?
I've seen similar issues when a new Hotfix or Patch version was installed.. NOT with a scan engine though... Just guessing here but....Most patches and hotfixes will stop the service completely which might generate a default setting upon restart.. In my experience, a new scan engine doesn't fully stop the service.
