Microsoft Research Builds 'BrowserShield'

"Researchers at Microsoft have completed work on a prototype framework called BrowserShield that promises to intercept and remove, on the fly, malicious code hidden on Web pages, instead showing users safe equivalents of those pages. The BrowserShield project, an outgrowth of the company's 'Shield' initiative, could one day even become Microsoft's answer to zero-day browser exploits such as the WMF (Windows Metafile) attack that spread like wildfire in December 2005."

Of course, this has to be a good idea.. Until they get a flood of complaints from webmasters as it incorrectly fingers their websites as containing malicious code. I will stick with Opera as a web browser thanks.
