And how is that different than a wired connection?? Wired or wireless, any PC is vulnerable.
True. But I prefer to minimize the risk as much as possible.
I do banking and other personal business on my PC. My primary PCs security is a bit of a pain to set up in the beginning but once done it requires very little further input from me.
Those overly complicated cryptic passwords and I have never got along.
Eight or more mixed charters is usually considered sufficient. Many people will use a simple sentence. < Easy to remember but the usual methods that crackers use will have a very difficult time with it. Mix in a capital letter or two. Replace the letter O with the number 0. An E with a 3 an h with a 4. Not real hard to remember but that much more difficult to break.
Then write it down. Also put it in a simple .txt file. Keep the txt file on a flash drive. When needed it`s a simple matter to copy and paste the password into the necessary places as opposed to typing it.
AFAIC, there is too much paranoia out there, mostly spread by these AV software companies doing everything to sell their overpriced programs.
WPA and AV`s are two totally different things and totally unrelated other then both having to do with security.
As well as many very capable and respected AVs offering free versions.
Having a 'open' WiFi doesn't automatically open you any more to an attack that having a wired connection. Assuming you have your system with a username and password and an internal Firewall.
The firewall does help protect the PC. It does nothing to protect the data being transmitted via a wireless connection.
All that does is allows someone to access the Internet. If someone wants to park in front of my house and send a e-mail, so what? If he wants to 'hack' my PC, he can do it from home.
And what ever that person is doing while using\stealing the service you are paying for, should it be illegal, even though not targeting you personally can be tracked directly back to you through your ISP.
You can swear all you want that it was`t you. But I seriously doubt the piggy backer will step up and take the blame when the Authorities come knocking on your door.
