Symantec Email Proxy constant notice

My day started with my symantec endpoint protection detecting two trojans, one of them the ZEROACCESS  wich i succesfully removed a week ago. After restarting, the threat was not found again. Then it detect another trojan, wich was removed by the antivirus by restarting. But now my problem is that a aproximately five notices from  SYMANTEC EMAIL PROXY appear. I close them but they reopen again. I don't use outlook express or anything that conencts my emails with the antivirus.

 

What can i do take off this notices? Are them evidence of something bad happening in my computer?

 

 

thank you.
