I'm trying to download something. But I want to use WI-Fi I don't know my neighbours wireless pass code and I'm not sure if my neighbours do have WI-Fi. I'm thinking about using the unsecured WI Fi. Is it a good idea. Will I might get a virus. I would like to know if its safe and if its a good idea.

All unsecured networks may be safe or not safe, because some people dont know how to keep a secured network and some knows but they might hack your smartphone data if they are professionals in hacking.

If you are on unsecured network browse at your own risk one more thing is that you mush have installed a good antivirus in smartphone if you are on unsecured network you will safe. Moreover totally depends on what you are browsing and downloading, say you are downloading any files from mail that's quite natural or you are copying the shared file that might be risk because the file is network may or may not contain virus.

If your device is loaded with antivirus it will safe for you and you can access any type of file or website, it warns you if that is an inappropriate file. One more important thing is you need to update the virus definitions atleat once in a week.

Tip :- dont list your passwords, userid's and credit card numbers and other credentials in you smartphone or in email or in any cloud storage

I turned on wifi and scanned for networks. A couple of unlocked networks came up, I don't know if it was theirs, but I tried connecting to those, it got through but then brought me to a bunch of companies like time warner cable, xfinity....etc, and asked me for a username and password, is this normal? is all unlocked wifi hotspots like this? I don't have any WiFi accounts, how can I connect? any help is appreciated. thank you.

When I visited on the road and I turned on Wifi found so many networks some are secured and some are not. When I try to connect to Internet, it is connected and once after checking whether Internet is working or not, it worked.

After checking the details of the wifi network they did not assign the network key and so anyone access. Some networks are asking me user id and password and login page is opening, may be that login page is created by them. I found that it is Star hotel, when I checked that if you are into that hotel they will provide a user id and password until we are in that hotel and for customer they are setting the session times.

Not all hotspots are secured or non secured, if that is a mall you can avail free internet.
