Beware, malware. The Windows AutoRun updates for Vista and XP SP3 that Microsoft released in February have so far proven successful in thwarting your file corrupting ways. Although Windows 7 was updated to disable AutoPlay within AutoRun for USB drives -- freezing the ability for a virus to exploit it -- the aforementioned versions had remained vulnerable up until right after January. Fast-forward to the period between February and May of this year, and the updates have reduced the number of incidents by 1.3 million compared to the three months prior for the supported Vista and XP builds. Amazingly, when stacked against May of last year, there was also a 68 percent decline in the amount of incidents reported across all builds of Windows using Microsoft's Malicious Software Remove Tool.
