I don't know a lot about computers but Google is my home page, LOL! I did a search for safety using WIFI and got some suggestions.
1- Turning off file sharing
2- Make sure the firewall is turned on.
3- Use SSL or HTTPS for sensitive material such as signing in to any website.
4- If using the computer in a WIFI area but not connecting to the internet turn off the WIFI card in the computer so others cannot connect to you.
The reason I asked this in the first place was because we were sitting in a Panera Bread store the other day and they had free WIFI. I asked about connecting and they said no password, find Panera and login. Then while eating I notice others on computers and then it hit me that this might not be secure. I could see me signing in to SOC and somebody getting my password. Oh the damage they could start then, LOL!
I really think WIFI is great if used with care but stuff happens to nice peeple. Like my SIL that called tonight and has DNSChanger Malware on her computer. All it takes is a relaxed attitude to become a victim.
I'll return this thread back to it original settings.
