I'm a very computer savvy guy (although not very networking savvy), and I may still be wrong about this, but I think my home network may be compromised somehow. I'd like to know if it's possible for someone to have hijacked my network's connection to Google.com and other popular websites.

Update: The issue seems to take effect with all popular websites. I can connect to small (non-popular) websites without issue, but Facebook, Google, Yahoo, and Bing cannot be accessed by any device on my home network.

On all devices using my home network, I'm being shown

http://www.google.com WARNING! Internet Explorer is currently out of date. Please update to continue.

when I attempt to connect to google.com.

I wouldn't be surprised by this at all if it were just the laptop. It's the fact that this is happening on all devices on my network that confuses me.

Here's the screenshot from my iPhone, for reference.

• Can my home network be compromised? Is that even possible?

• How can something like this happen across all platforms on all devices in the same way? I wouldn't imagine every device / platform on the network would get the same virus.

• Should I assume that my network's security is totally compromised?

Update: All mobile devices and laptops on my home network are experiencing the same alert when attempting to connect to google.com.
