Computers Worldwide Targetted by a MBR Worm

WARNING - This threat returns to the ways of old - IT DESTROYS DATA!
Initially perhaps conceived as a prank targeting a small community of bikers in central Slovakian region, the worm Win32/Zimuse.A and Win32/Zimuse.B has achieved worldwide notoriety. It is a type of threat that overwrites MBR (Master Boot Record) of all available drives with its own data, making the data stored on the user’s computer inaccessible. Moreover, the restoration of the corrupted data is complicated, requiring specialized software or a provider.
Since the worm’s inception, ESET has detected it on hundreds of computers of its users. Initially after the outbreak, only users in Slovakia were affected – accounting for over 90% of all infections. Presently, the greatest number of infected computers is in the United States, followed by Slovakia, Thailand and Spain, followed with Italy, Czech Republic and other European countries.
