This morning Google kinda went haywire and all the results for my search had a message "This site may harm your computer."
For fun, I entered "Google" into the search bar and got the same results.
Note: Click on any of the screen images for a larger size.

Clicking the link led to a warning page.

A quick search on Twitter confirmed it wasn't just me.

Very quickly the hashtag #googmayharm started to be used so people could share stories and screenshots via Twitter and other social media sites.
Google does so many things so well, that it is sort of fun to catch them with a little hiccup. Just shows that we all have issues.
