Google has just announced something pretty interesting, that it is using its own data to detect viruses, using Google Search to warn users if their computers are infected with a specific form of malware. Users infected with the virus will see the above warning.
From the Google blog post curiously titled “Using data to protect people from malware”:
“Recently, we found some unusual search traffic while performing routine maintenance on one of our data centers. After collaborating with security engineers at several companies that were sending this modified traffic, we determined that the computers exhibiting this behavior were infected with a particular strain of malicious software, or “malware.” As a result of this discovery, today some people will see a prominent notification at the top of their Google web search results.”
