My Internet Connection

Okay. I had been enjoying my wireless connection... until of late. Sometimes, my connection just shuts off. The good thing is, I have a neighbour (I don't know which one) that opens their wireless connection 24/7. And it's unsecured... meaning it doesn't require a certain network key to be able to connect with it. However, that neighbor, although the wireless connection is open, put a name Virus next to it's name. LOL. Are they trying to ward off other users? Probably they think if they put a virus term instead of other names, it would prevent others to use their connection? They are really funny. Anyway, I have been using their connection for almost a month now. We may need to buy a new wireless router or modem soon. I hope it's not considered stealing... to use other people's wireless internet without letting them know.
