Malware? Spyware?

Hey all,

I've got a problem that just started a few hours ago, and I'm not sure what is causing it. My best guess, is that it is malware of some sort.

Since a few hours ago, my computer has started doing something odd. Some sites that I go on, are acting rather strange. Ads are coming up in Spanish, even though I am using a computer that has it's default language as English, as well as having my browsers set to English. Netflix, when I tell the computer to play, is showing the title in Spanish, but only after the play button is clicked.

I ran CCleaner thinking maybe a cookie I picked up was causing it or something, I ran malwarebytes and Kaspersky full scans, and nothing was found. I tried doing a system restore to before it happened, and it didn't change anything.

Any help would be greatly appreciated, as I'd like to get rid of whatever is causing this.
