Google thinks every result is spam/malware?

I’ve turned my computer on today gone to search google and found that all the results have a warning under them…

“This site may harm your computer”

even amazon… what are google doing to me?

Clicking on them gives me a google page that blocks me access to the page. 🙁

Google reckons all it's results are harmful

It would appear that I am not the only one, Google is actually broken, someone’s committed some broken code, whoops.

Theres loads of threads on the Google support forum about this.
