When the first version of Microsoft Corp.s new malicious software removal tool is released on Tuesday, it will be pre-programmed to zap 10 of the most virulent worms and viruses, including Blaster, Sasser, MyDoom and Nachi.
As previously reported, the tool will be released as a “critical” download and updated once a month as part of Microsofts scheduled software patch cycle.
According to a note released to Microsoft MVPs (Most Valuable Professionals), the initial version of the tool, code-named Titan, will be able to detect and delete the Blaster, Sasser, MyDoom, DoomJuice, Zindos, Berweb/Download.Ject, Gailbot and Nachi viruses.
In the event of a major worm or virus outbreak, Microsoft will push out updates for the malicious software removal tool outside of the monthly cycle, according to Amy Carroll, director of product management in Microsofts security business technology unit.
The tool will also be pushed out to Windows users as a download through the Microsoft Download Center. Customers who have Automatic Updates turned on will automatically receive the download.
It will also be made available as an ActiveX control on a malware removal section of Microsofts home page.
The tool is programmed to scan a PC for infections of known viruses, but it is not intended as a substitute for full anti-virus protection. After a scan is conducted, the Microsoft tool will present color-coded results: a red X for an infected machine or a green checkbox if nothing is detected.
Anti-virus vendor McAfee Inc. also provides a similar tool called Avert Stinger. Stinger, available as a free download, uses scan engine technology, including process scanning, digitally signed DAT files and scan performance optimizations, to disinfect systems.
