Financial terms of the purchase, which included GeCAD's intellectual property, were not released.
The Bucharest, Romania-based GeCAD makes software for anti-virus detection and data security. With GeCAD's technology built into the Windows platform and other Microsoft-branded products, the software giant could emerge as a major competitor in the network security space now dominated by Computer Associates, Network Associates and Symantec.
The company did not provide additional details of its anti-virus software plans.
The GeCAD acquisition comes amid Microsoft's all-out Trustworthy Computing initiative it launched to counter embarrassing publicity over a string of security glitches in some of its key software. "The GeCAD acquisition is an extension of these [Trustworthy Computing] efforts," Microsoft said.
Just last month, Microsoft teamed up with Network Associates and Trend Micro to launch a Virus Information Alliance (VIA) Web-based repository for information on viruses affecting Microsoft's technology.
In April this year, Microsoft also launched a new Windows File System Filter Manager Architecture aimed at simplifying anti-virus software development.
