Virgin Media has begun informing customers on its network if it thinks their computers are infected with a Trojan called SpyEye, the ISP said on Thursday.

In an initiative launched in August last year as a response to the threat of the Zeus Trojan, the company is working with the Serious Organised Crime Agency (Soca) and other third parties to warn customers of infections. SpyEye collects personal and banking information and is "comparable in severity" to Zeus, Virgin said in a statement.

"Cybercrime is on the rise and the increasing sophistication of malware infections mean that all internet users could be at risk with devastating effects," Virgin Media broadband chief Jon James said in the statement. "We are taking this proactive approach to help protect our customers and to provide them the support and advice they need to stay safe online so that they can enjoy the best of the internet without the worry."
