Change your router's password.

And then change the password needed to access the network.

first, change the SSID to something non personal but different than
what it was configured for at the factory.

then, setup WPA2 as security or at least WPA

then change the router password

I hate to suggest this, but you may already have had data theft,
malware or more.

was there a name for this 4th computer?

The other pc was named user-E3FE7BEC8A. After i saw, I turned off all the
network pc's and rebooted the router, the 4th pc was not there after reboot.
I changed the SSId and passwords this morning.

Dont forget to hide your SSID.

No, this is a common misconception. Not broadcasting the SSID provides no
security benefits and causes connectivity issues. The SSID should be
changed to something non-personal but recognizable - as MS. Bowman says -
and should be broadcast. The encryption should be the highest level
supported by all devices on the network and that is where the security
comes from.

Hiding the SSID does nothing for security. It is easily discovered.
