Aside from the fact that our US cousins are able to buy copies of the new Vista operating system for under 50 of our quids, when PC World are shunting out their boxes for twice this amount, there are big questionmarks about the security of the new operating system.
According to IT security vendor Webroot, its research suggests that Windows Defender is potentially ineffective in blocking.
On top of that, Webroot says that the Vista defence module also has slow definition updates and weak anti-virus capabilities.
Gerhard Eschelbeck, Webroot's CTO, said that Microsoft is to be applauded for the substantial improvements and exciting new features of Vista.
"The various built-in applications, networking enhancements, and improved graphics support make for an impressive product," he said.
"However, we want to make sure that users understand the Vista operating system's limitations, and caution them that Microsoft's default malware blocking application and anti-virus programs may not fully protect them," he added.
Webroot says its tests discovered that Defender failed to block 84 per cent of a testing sample-set that included 15 of the most common variations of existing spyware and malware.
On top of this, Webroot says that the efficiencies in the Windows Vista security system extend beyond its spyware blocking problems. Microsoft, says Webroot, currently issues spyware definition updates for its Windows. Defender product every week to ten days.
This doesn't fit well with the fact that Webroot claims that its threat research team identifies around 3,000 new types of spyware and linked malware a month.
Because of this, the IT security firm says that spyware definitions need to be updated at least daily and preferably hourly for maximum protection.
Somehow I can't see hordes of PC peeps rushing to upgrade to Vista just yet...
