AntiVirus software vendor McAfee Inc. have stated it is "greatly disappointed with the lack  of action" on Microsoft Corporation's part to provide information needed to develop security software for the new Windows Vista operating system.

According to Microsoft, both McAfee and Symantec Corp. were given sufficient information to make their products work with Vista, and the software interfaces for the Windows Security Center were uploaded to a website for software developers.

Symantec and McAfee have accused Microsoft of abusing its monopoly in deciding which security products can run on Windows Vista, arguing that Microsoft is deliberately withholding information needed to develop products that work on the new system.

Microsoft Windows Vista is a new operating system and will be available to consumers early of next year.
