Loss of spam filter

In a recent "upgrade" the spam filter for Outlook disappeared and when I finally pinned a "chat" guy down he said;

Peter, I am sorry to hear that, I am afraid to inform you that according to the new update the new Norton version will not support the Antispam feature for Emails.

That to me looks like a downgrade.

I have tried twice to complain but get no response.  I am either going to have to accept this and renew or go through the pain of uninstalling.  The last time I did an uninstall of a virus product it trashed the computer. 

Any help welcomed!

Peter
