Google warns users of malware infectionsInfected PCs routing traffic via proxy servers

21 July 2011

Google has 87.3% of the web search market in the UK

Google is using prominent notices on its search engine results pages to warn users that their machines are infected with malware.

In a posting on the Google Online Security Blog, Damian Menscher, a Google security engineer writes: ‘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 behaviour were infected with a particular strain of malicious software, or malware.’

Menscher went on to add that that malware was causing infected computers to send traffic to Google through a small number of intermediary servers or proxies.

Menscher said anyone using an infected machine would receive prominent notification at the top of their Google web search results page, warning them of the fact.

‘We hope that by taking steps to notify users whose traffic is coming through these proxies, we can help them update their anti-virus software and remove the infections,’ Menscher added.

He ended his blog posting by advising users who were concerned that their machines maybe infected but who weren’t getting notification, to run a system scan on their computer. This would tell them if they were.
