I downloaded the latest Firefox security update and my computer will no longer access the internet in any fashion, despite the fact that I'm still connected to the internet. Other browsers no longer work either.
Immediately after I downloaded the latest firefox security update my computer will no longer access the internet. I still have a fine wireless connection but Firefox, Internet Explorer, Itunes, and every other program will no longer access the internet, saying there is a connection error. I even tried restoring my system to a previous date but it said that a security program was preventing it from doing so.

What's the security program called? Is it Win 7 Security by any chance? There's a rogue AV app that will prevent internet access by that name. It comes in many different flavours, but it's basically the same product with different names depending on the operating system its aimed at. See screenshot.
Do you have another computer you can use to download Malwarebytes? Or can you get a friend to download it for you and copy it to a USB drive? Download from here: http://www.malwarebytes.org/products/malwarebytes_free
You can use the USB drive to transfer the program to your own PC and then install it.

I will try Malwarebytes. And I can't find the security program, or any other recently downloaded programs for that matter. All I know, is I downloaded the new Firefox update and everything stopped working.
It's possible that your firewall blocked the Firefox connection, but it wouldn't block access to IE, iTunes and other programs. See Configure firewalls so that Firefox can access the Internet just in case it's of some help, but it doesn't sound like a firewall problem somehow.
Did you download Firefox from Mozilla @ http://www.mozilla.com/ ?
Malwarebytes fixed it! Thanks!
You're welcome.
