Found WiFi Turned On - Security Problem?

I was checking the battery of the wireless mouse via the top bluetooth menu and accidentally clicked on the wifi menu in error. I found that the wifi was on; however, I don't use wifi as my Mac is connected via a ethernet cable to a routher that is connected to a wall jack for a fiber optic cable connection.

If you look down the wifi menu itself I see three things listed as follows:

DIRECTV_WVB_401573D6 (followed by a little lock symbol and a wifi icon)

Dont Even Try It!!!! (followed by a little lock symbol and a wifi icon)

NETGEAR88 (followed by a little lock symbol and a wifi icon)

The above is followed by three other menu items:

Join Other Network...

Create Network...

Open Network Preferences...

So has someone turned on my wifi by physically accessing my computer and then connected to it? I checked my router and it says only my computer is connected physically to the router at least. I've turned off the wifi for now.

Sorry if this question is for nothing, but awhile back someone attempted to break in using a garage door code reader. They opened both doors for a four car garage to get in, but then sped off after they saw one car was left inside (one person happen to be home sick in bed).
