The MSBlast worm, also commonly called the Blaster worm, started spreading last August and is believed to have spread to hundreds of thousands of systems.
While most corporations have cleaned up the worm, Microsoft has found that a large number of home users are still unknowingly infected, the software giant said in a statement.
“For many users in this situation, there is little indication that they are infected other than possible performance degradation,” Microsoft said in a statement. “And those infected are still actively transmitting the worm, causing Internet congestion in the process.”
Microsoft’s aim in releasing the latest tool is to reduce the amount of traffic being born by ISPs by cleaning up a significant number of home computers.
The tool can be found on Microsoft’s download site.
