Multiple security events..advapi logon process...my computer secure?

Hi,

Hopefully someone can help me out with the following. I just had the fake Windows Security Center virus/malware (aka: sysguard variation) on my computer. After much headache I was able to get this removed (I think).

What I found was that my router had another port set to be allowed which I quickly removed.

What I am seeing now is that in the event viewer of both my wired and wireless pc is a bunch of security events.

They first start off with loading a bunch of authentication packages when I log on. Is this normal?

After that is the start of many:

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

I then have a whole bunch of exceptions added to windows firewall entries. (I have windows firewall turned off by the way)

And then I have this entry which is also puzzling:

Successful Logon:
User Name: Bear
Domain: BEARNEW07
Logon ID: (0x0,0x338C0)
Logon Type: 2
Logon Process: User32
Authentication Package: Negotiate
Workstation Name: BEARNEW07
Logon GUID: {00000000-0000-0000-0000-000000000000}

Can anyone help me out to confirm what these are? Is this normal? Does anyone else have these events listed?

Thanks

Please let me know if you need more info.

XP SP 2

update:
So I've done full scans on both computers with anti malware, adaware, avg, spybot and hijack this. I think Im clean in terms of malware and spyware. However the above is still a problem, I have multiple repeating security events and can't find if those are normal or not.

 

Hi
I have a lot of the same events on my system also.

Hi, Barry2616,

Methinks you need to go to W Update ASAP and let MS tell you what critical updates this system is missing and download all of them.

If "XP SP2 " was not a typo, this system is in harm's way.....given we are on our way to SP4.

Edit: None of my systems are on autoupdate, but perhaps yours should be? A lot of people choose that. Your call, but you MUST HAVE THE CRITICAL UPDATES be it on auto or visit them on Tuesdays.
