Microsoft has published interesting data on the Microsoft Technet blog, which shows a significant decrease in computers infected with autorun viruses. According to Microsoft experts, the decline is quite significant, the world has become 1.3 million less infected with this type of malware. The statistics displays data from February to May of this year, and compared Windows Vista and XP.
The comparison was made with the number of infected PCs in the previous three months. Experts from Microsoft have fixed the constant growth of the “species diversity” of such malicious software, which has become increasingly common due to the appearance of flash drives, external hard drives, memory cards and other equipment on the hardware market. The most popular types of autorun malware, according to Microsoft, are Conficker, Rimecud, and Taterf.

Starting in February of this year (approximately from the middle), Microsoft released and began distributing updates to the above operating systems, which did what it was time to do: they blocked the autorun function. Following the release of updates, experts began to notice a decrease in the number of infected PCs.

Microsoft also claims that in May 2011, PCs with operating systems such as XP and Vista were 59% and 74% fewer infected, respectively, than in May last year. At the same time, representatives of Kaspersky Lab claim that the activity of representatives of the “families” of Palevo, Autorun, Kido, and Magania decreased only by 15%.
But still, despite the fact that the data collection and processing systems of Microsoft and Kaspersky are different, a decrease in the activity of autoran-malware is noted by both companies. And the decline is quite significant. It is too early to talk about victory, but there is success.
