SBS Server 2003 unusual logons

I have an SBS server 2003 and in the Event Log/Security I see logon/logoff activity for user names that are not on the system e.g. COM4$, LEITRIMLADY$ etc.
Are these genuine ?
If not how do I remove them.
There is a full anti-virus running up to date on the server.

Thank you. I was concerned because the anti-virus had been removed from the system and there is no explanations for that.
