Few minutes ago I was searching something on the web, and suddenly Google results are a list of page with the advice that every single site may harm my pc.
Seems that someone* trying to update the servers at Google did some mistakes while he was live-patching the memory of the whole Google infrastructure. Please fix that as soon as possible!
To get it work in the while they fix this problem you should use Scroogle, a Google proxy.
