The worm has affected many businesses worldwide, crashing PCs to crash..
The Software Removal Tool is usually updated as an addition to Microsoft’s monthly patching cycle, just gone, but the company deemed that Zotob should be tackled now instead of waiting for next month’s usual update.
Zotob takes advantage of an already patched Plug and Play flaw in the Windows operating system, and versions of Windows 2000 are particularly susceptible to the vulnerability.
The Zotob variants responsible for infecting machines were accompanied by other worms, as yet not individually tackled by Microsoft.
Microsoft said users who had already installed the Plug and Play patch would be protected from all the different worms.
A number of anti-virus software companies had already blocked Zotob with their own products.
