An alarming number of Windows users are needlessly opening themselves up to attacks by rootkit and worm malware by turning off the User Access Control (UAC) that comes with Windows 7 and Vista, Microsoft has reported.
A new blog by researcher Joe Faulhaber of the Microsoft Malware Protection Center offers no hard numbers on how many users might be doing this in total, but said that one recent day nearly 23 percent of PCs it had found to be infected by dangerous types of rootkit and worm were machines on which UAC had been disabled.
