Anonymous Logons

Hi, I posted a thread in the malware section but Kestrel13 said I should post it here to find out what's going on with my computer. I found anonymous logons in my security log and I have no idea what they are. Do I need to attach any scan logs here?


Type: Success Audit
Date: 1/20/2011 (there were a number of dates going back as far as two years, maybe more)
Time: 3:42:36
Source: Security
Category: Logon/Logoff
User: NT AUTHORITY/ANONYMOUS LOGON

And there was a number: 540

I also found a 1394 net adapter connection that I never had before. I don't know what it is or what it does so I disabled it. My connection is still fine so I don't think I need it, though I would like to know what is and how it got there. I don't have wireless so if it's a wireless adapter or whatever, why is it there? Sorry if these are really stupid questions, I try to read about this stuff, but all the info is conflicting. One site said the anonymous logon/logoff 540 is just the machine logging itself out after I do. Another site said someone may be hacking my computer. I'm just confused.

 

Have you installed anything new lately?

 

Do you have a Firewire adapter and run Windows XP, by any chance?

 

Besides installing a new comodo firewall yesterday, I installed VobSub less than a week ago. But the anonymous logons go back for years in the security log. They always have the same code too, "540", if that means anything.

I don't know if I have a Firewire adapter, I don't even know what that is. :-o

I do run Windows XP, yes.

Should I run a scan of something for you to look at?

Thank you, both of you, for your help!

 

thank you! I had read a similar article but there were twenty other articles that said something different.

You guys are great, this forum is a godsend.

 

You probably have one. Since you've disabled it, it shouldn't be an issue.

 

times zillions!!!
