Google (GOOG) is beginning to notify users of their search engine if they are infected with a certain type of malicious software that has been spreading around the Internet.

In a Tuesday blog post, the Mountain View company announced that they had detected unusual search traffic. Upon investigation, engineers found that the traffic was being sent by computers infected with malware; the computers would go to Google through intermediary servers, or “proxies.”

To fight this virus, the company has begun notifying anyone using their search engine if they are reaching the website through the suspicious proxies. At the top of a Google search result from a possibly infected computer, a message states “Your computer appears to be infected.” Google also provides a link to a help center article to learn how to fix the problem.

“We hope that by taking steps to notify users whose traffic is coming through these proxies, we can help them update their antivirus software and remove the infections.” engineer Damian Menschler said in the blog post.
