Windows Vista not secure at all

Security systems vendor Sophos said there are at least three malware creations that can infect computer systems running on Microsoft's Windows Vista operating system. Two of these malware date back to 2004, said Sophos.

It said the three are internet worms -- Stratio-Zip, Netsky-D and MyDoom-O -- and are capable of executing on Vista. MyDoom and Netsky variants had come into circulation sometime in 2004.

Sophos said Vista's Windows Mail Client is capable of blocking the worms, but systems running third party email clients or permitting web-based mail services like Yahoo are very much vulnerable. Sophos explained that Windows Mail Client can block these mass-mailers as it can detect double extensions.

Microsoft's long-awaited Windows Vista release Thursday for business customers will get more than just the passing attention of network administrators. That's because hackers will be eagerly waiting to do what hackers do best: start some mischief.

The software that took $7 billion, five years, and armies of programmers is now going to be the target of hacker attacks looking to prove a point: that no Microsoft software is secure.

It's also a chance to prove Microsoft CEO Steve Ballmer, who's made some bold security claims, dead wrong on Vista.

The Vista-resistant malware - Stratio-Zip, Netsky-D and MyDoom-O - comprise 39.7 per cent of all malware currently circulating.
