The biggest story this week for V3.co.uk readers was Nokia's denial that it will be switching from Symbian to Google’s Android mobile operating system for its next smartphone.

The denial was prompted by a report in The Guardian citing " industry insiders" claiming that Nokia was developing an Android-based touch-screen device.

Elsewhere, Microsoft has been warning users to update their systems following the discovery of a new attack targeting an Internet Explorer ActiveX component. Attacks are targeting a flaw in the Microsoft Video ActiveX control.

The other big news this week has been Google’s announcement that it will be releasing its own operating system, although the general industry response has been that the search giant’s Chrome OS will not pose a huge threat to the dominance of Microsoft Windows.
