To combat the malware, security experts recommend disabling AutoRun on all Windows operating systems and restricting write permissions to file shares. Depending on the AV vendor, the malware has several names, including W32/VBNA-X, W32/Autorun.worm.aaeb, W32.ChangeUp and WORM_VOBFUS.
The latest outbreak arrives about a year and a half after Microsoft reported big declines in AutoRun infection rates. In the first five months of 2011, the number of AutoRun-related malware detected by Microsoft fell 59% on XP computers and 74% on Vista PCs, compared with 2010.
