Event viewer - security log ?'s

[Bear28]

Hi,

I don't normally do this but since everyone is usually friendly and helpful on here I figured I'd give it a shot.

I recently had some virus/malware that I got rid of, but Im noticing a whole bunch of security logs in the event viewer that I'm unsure of. They seem to repeat over and over.....and over.

Here are the main 2 that I'm seeing. Does anyone know if these are normal or not?

Successful Logon:
User Name: NETWORK SERVICE
Domain: NT AUTHORITY
Logon ID: (0x0,0x3E4)
Logon Type: 5
Logon Process: Advapi
Authentication Package: Negotiate
Workstation Name:
Logon GUID: {00000000-0000-0000-0000-000000000000}

Special privileges assigned to new logon:
User Name:
Domain:
Logon ID: (0x0,0x3E4)
Privileges: SeAuditPrivilege
SeAssignPrimaryTokenPrivilege
SeChangeNotifyPrivilege


Thanks
