Why can't I get on my Facebook?

Sounds like a virus that's proxying you to other sites.

I would immediately run Avast! and Malware Bytes (personally).

You could also check msconfig by either searching "msconfig" in the start bar, or by going run -> cmd -> msconfig.exe

In msconfig, go to your startup tab, and disable everything, then select things you KNOW you WANT on startup (typically nothing, and this will speed up your startup time DRASTICALLY).

you could try some other various antivirus, however I find Avast! and Malwarebytes to be good, reliable, and they both have free trials.

You could also try clearing your cache. Depending on your browser you can go through your settings and clear all cookies/browsing history/cache/saved passwords/etc. This could be a possible solution to your problem as well. If you wanted a thorough sweep of this, you could run CCleaner too.

Good luck!

Edit: To contradict other statements made by other people:
If your getting connection to other sites there's nothing wrong with your cords, or modem or router.
If your getting connection through your Ipod, then your ISP isn't blocking it (assuming your using Wifi in your house.)

That rules out anything but a virus, really. Unless someone has installed a "net nanny" type program to prevent users on that computer from going to facebook.
