BleepingComputer.com: Firewall question

Alright had something that i dont think i've seen before,had windows firewall turn itself off.
I was running a Download Mananger from Fileplanet at the time,never had it do that before though and it didnt do it at first,and hasnt done it since.
Now i just reformated the computer yesterday,and havent went to any websites but here and a few other places(that i trust)
Im not using any other firewalls at the moment i know that can cause them to do that.
But here are a few log's from my security folder in Event Viewer(not sure if these are normal or not)

This event is generated when a logon session is created. It is generated on the computer that was accessed.

The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.

The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network).

The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on.

The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

The authentication information fields provide detailed information about this specific logon request.
- Logon GUID is a unique identifier that can be used to correlate this event with a KDC event.
- Transited services indicate which intermediate services have participated in this logon request.
- Package name indicates which sub-protocol was used among the NTLM protocols.
- Key length indicates the length of the generated session key. This will be 0 if no session key was requested."
