Is this due to people with viruses/compromised routers going to their home screen (google) and having that redirected to some malicious page?
Someone briefly had a pointer to http://www.google.com/safebrowsing/diagnostic?site=code.goog..., which includes:
> Malicious software is hosted on 23 domain(s), including sms-bomber.googlecode.com/, gdata-issues.googlecode.com/, infojob.googlecode.com/.
I would actually compare it to github.com and github.io http://www.google.com/safebrowsing/diagnostic?site=github.co...
