Oracle 10g and internet connection

Question

I recently installed a program which uses and installed the Oracle 10g database, but cannot run the database while I have an internet connection. If I disable my internet, I can run Oracle and my program. If I am connected to the internet and run the program it pops up this box:
DATABASE LOGIN FAILED
+... due to Oracle condition:+
ORA-12541: TNS:no listener
OK
When I click Ok, it pops up a new box with 2 tabs: one asking for me to:
Choose a (named database)
This installation stores data in a named Oracle database.
Since you may have several such databases, please select the name of
your desired database from the list below.
Note: If you are connecting to a local, single-user database, it may not have
a name, or its name may not work.  In that case, you would need to choose
the entry "<<always use default>>".
There is a drop down box with 3 choices for the Database to use for this installation: XE, ORACLR_CONNECTION_DATA, and <<always use default>>
The other tab is:
Describe Privileged Account
For maintenance purposes, this system also needs the name and password of
a privileged Oracle user account.  It uses this privileged account
only as needed, for various setup and maintenance tasks, such as
o     creating the application's user account,
o     providing it with storage space,
o     providing backup/restore services,
o     applying software updates.
Please enter the privileged account's name and password below.
If you do not know the account's name and password, please contact your
Oracle database administrator (DBA).
And it is asking for a user name and password. The Oracle help said that info should have been displayed somewhere during the Oracle installation process, but being as though I installed another program that did the Oracle, I don't think I ever saw it.
I think it may matter:
XP Pro SP 3
2.4 GHz processor
3 GB RAM
To summarize; is there a way to run the Oracle database and my internet connection?
Finally, I apologize for likely not providing all you would need to answer my question, I will provide anything else I can if it will help.
Thanks

Hi, thanks for the quick response.
I went through the steps in the loopback adapter installation link you provided and have added a loopback adapter. When I do the ipconfig/all I get the following for the loopback adapter:
Ethernet adapter Local Area Connection 4:
Connection-specific DNS Suffix.....:
Description...............................: Microsoft Loopback Adapter
Dhcp Enabled...........................: No
IP Address...............................: 192.168.25.129
Subnet Mask............................: 255.255.255.0
Default Gateway.......................:
So it appears that is good to go. The issue still persists. Below is system information and Oracle information.
