Microsoft has won court endorsement to shut down a global network of computers which it says is guilty for more than 1.5bn spam messages every day.
A US judge approved the firm's request to shut down 277 internet domains, which it said were used to "command and control" the so-called Waledac botnet. A botnet is a network of infected computers under the control of hackers.
The firm said that closing the domains would mean that up to 90,000 PCs would stop receiving orders to send out spam.
A recent study by the firm found that between 3-21 December "approximately 651 million spam e-mails attributable to Waledac were directed to Hotmail accounts alone".
It said it was one of the 10 largest botnets in the US.
Machines in a botnet have usually been infected by a computer virus or worm. Typically, users do not know their machine has been hijacked.
Microsoft said that although it had successfully shut down the network, thousands of computers would still be infected with malware and advised people to run anti-virus software.
The court order was part of what was called "Operation b49". <\p>
Microsoft said it was the result of months of analysis and described it as a legal first.
"This action has quickly and effectively cut off traffic to Waledac at the .com or domain registry level, severing the connection between the command and control centres of the botnet and most of its thousands of zombie computers around the world."

After just two days, spammers hit Google's social networkIn spite of only being launched this week, spammers are already aiming Google Buzz, the search engine's social network, says Websense.
"It's disturbing that spammers have an better knowledge of social networks these days that allows them to hit new services like Google Buzz so rapidly," said Carl Leonard, security research manager at Websense.
"To embrace social networks like Google Buzz safely, businesses need to defend themselves and their employees with a security solution that keeps up with constantly changing web content in real time."
Websense is recommending web users to use care when clicking on unknown links. It also revealed it hopes Google is prepared to deal with the volume of spam it is bound to see on the new service.
- Avoid clicking on doubtful links in e-mail or instant messages as these may be links to spoofed, or fake, Web sites.
- Never fill out forms in messages that ask for personal or financial information or passwords. A reputable charitable organization is unlikely to ask for your personal details via e-mail. When in doubt, contact the organization in question via an self-governing, trusted mechanism, such as a verified telephone number, or a known Inter-net address that you type into a new browser window (do not click or cut and paste from a link in the message).
