I wonder whats up with Google today, any search I make, it says “This site may harm your computer”
I checked for any security setting, and ever logged out Google, but the result is the same .. so it’s either a setting I cant find, or Google is indeed experiencing “technical difficulties” 
Here is an example, even Apple’s discussions board is flagged (notice the warning under each page name).
Yeah, Google had a brief mammaries vertical moment.
See their blog post about it
