Error restarting pop3 on ms exchange server

I recently installed trendmicro virus scan  (I'm not sure if this could be the cause)

I was then installing an upgrade to scan exhcange server and it requested restarting pop3 virutal server

I stoped the service and tried restarting it and it won't restart.  I keep getting this error

The service could not bind instance 1.  The data is the error code.

pop3svc  is the source
115  is the eventid

this is quite critical any help would be great asap

IMAP4 virtual server is stopped and won't start either

all the virutal servers are set to unassigned ips and each have there designated tcp ports

I didn't have this problem until after I installed the virus software

Do I need these serverics running for exchange to work?

Email seems to be working even though these 2 services are not started but I would like to fix this problem

I had the same problem.
Disable the ones that will not start.
Create new ones and make them the defaults.

what delete the ones that won't start there isn't anything to disable?  

are the settings default settings?  or do I have to copy them over?

How do I set as the default?
Same answer as your other question: You most likely installed the client version of Trend Micro (for Outlook clients conneting TO an Exchange Server) and not the Exchange SERVER version. The reason is that yor anti virus software is blocking the ports Exchange needs to start those services. See;EN-US;Q292522 for more info.
