Keith,
thanks for sharing the link to that report. It has come a long way since
the one I looked at a while back for the year earlier period. The
detailed report has some excellent visuals to summarize the data.
Although Microsoft Windows Vista seems to be taking a lot of reputation
"hits" in the market for performance related issues, the commentary on
p46 of the full report suggests that the security improvements in Vista
ARE working:
> The MSRT has proportionally cleaned malware from 60 percent less
> Windows
> Vista-based computers compared to computers running Windows XP
> SP2. Similarly,
> the MSRT has proportionally cleaned malware from 91.5 percent less
> Windows Vistabased
> computers than from computers running Windows XP without any service
> pack installed. Users who employ User Account Control (UAC) on
> Windows Vista
> will fare even better given that UAC provides an additional layer
> of protection against
> socially engineered malware delivery methods that rely on
> administrative privileges
> for installation.
Best Regards,
John Holmblad
