I am running AVG 9 on our SBS 2008 server with Exchange 2007. This is a new installation of all these items. For the past week, mail delivery ceases or slows down from Exchange and I get a message in the AVG console: "E-mail Scanner for MS Exchange (SMTP TA) Stopped"
At this point, my only solution is to reboot the SBS server, then exchange starts working properly again.
Any ideas on how to fix thsi?
