As of approximately two days ago I started receiving an error whenever I try to access google. I am using Windows 7 and chrome (though the problem persists in IE and firefox). Instead of displaying the normal google homepage, it says "404 Not Found" as a header, with "nginx" printed underneath it. if I try to right click-->"search google for xx" I receive the following error:
Cannot connect to the real www.google.com
www.google.com has asked Chrome to block any certificates with errors, but the certificate that Chrome received during this connection attempt has an error.
Error type: HSTS failure
Issuer: COMODO SSL CA 2

I do have a roku, which I have unplugged after reading this message, with no effect. I get this same message on my other laptop, which leads me to believe it is a network issue rather than malware (these computers do not cross and rarely visit the same websites, though I cannot rule out the possibility). I have tried a system restore and Norton Power Eraser on recommendations I found using a bing search, neither of which solved the problem.
In addition, today I started having an issue accessing facebook. It seems to go on and off; right now I can access it fine but earlier today I was receiving this message:
The requested URL "/", is invalid.
I don't know if this is related or just a fluke one-off thing with particularly ridiculous timing (as I said, facebook is working fine right now).
I believe the issue might have started during a power-outage here, but again it might just be similar timing. This is all the information I feel is relevant but if anything else is needed please let me know. Any guidance would be very much appreciated.
