Google: to protect and serve
I just discovered that Google filters and blocks sites it thinks contains viruses or malware. That’s nice of them.
Here’s an example:
http://www.google.com/interstitial?url=http://www.hypnodude.com/
This is supposed to be Ron Stubb’s website, which worked a few weeks ago, but now appears to be removed from Google’s index. Despite the block, the listings may still remain in a top organic search ranking.
The only information Google provides is, ‘this site may harm your computer’.
How does it know? Are users contacting Google, or does Googles web crawler scan for virus code patterns?
