Oh look. what a suprise
http://news.bbc.co.uk/1/hi/technology/6058512.stmMicrosoft has agreed to provide code so that software companies can provide their own security add-ons to its Vista operating system.
Rivals had previously complained they were locked out from the security system for Vista.
Experts warned the lack of access increased the risk of malicious hacks and viruses.
The news that the software giant will now allow companies such as McAfee and Symantec access to the kernel of the 64-bit version of Vista has been met with cautious approval.
A sensible move. perhaps the delay was designed to obtain favourable terms from the anti virus vendors.
